With a population of over 144 million people, Russia is the ninth most populous country in the world. The official language of Russia is Russian, and the currency is the Russian ruble. Russia covers a total area of 17,098,242 square kilometers, making it the largest country in the world.
Studies aimed at developing methods for investigating the impact of industrial facilities on the air is of interest. The purpose of this work is to analyze the methodology for assessing the risk of exposure of a technosphere object to the atmosphere. It was assumed that the enterprise in emergency mode emits pollutants through the source of emissions at the maximum single concentration of the substance exceeding the maximum permissible concentration. To calculate the impact on a human, various scenarios of an emergency situation are taken into account. These are constructing failure trees and using well-known health risk assessment techniques. The calculation took into account the wind rose for a specific enterprise location and wind speed projections obeying the normal distribution law.
This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather. And the problem with passwords is that people tend to choose easy ones to remember such as "password" and "123456" , which are also easy for cyber thieves to guess. Select strong passwords that are harder for cybercriminals to demystify. A strong password is one that is unique and complex—at least 15 characters long, mixing letters, numbers and special characters. Make Online Purchases From Secure Sites Any time you make a purchase online, you need to provide credit card or bank account information—just what cybercriminals are most eager to get their hands on. Only supply this information to sites that provide secure, encrypted connections. As Boston University notes, you can identify secure sites by looking for an address that starts with https: the S stands for secure rather than simply http: They may also be marked by a padlock icon next to the address bar. Any comment or image you post online may stay online forever because removing the original say, from Twitter does not remove any copies that other people made. Indeed, they may not even be real.

They know people are sometimes tempted by dubious content and may let their guard down when searching for it. Corporate cybersecurity experts worry about "endpoints"—the places where a private network connects to the outside world. Your vulnerable endpoint is your local Internet connection. Make sure your device is secure, and when in doubt, wait for a better time i. Be Careful What You Download A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather. And the problem with passwords is that people tend to choose easy ones to remember such as "password" and "123456" , which are also easy for cyber thieves to guess.

Cloud security Cloud security provides similar protections to application and infrastructure security but is focused on cloud or cloud-connected components and information. Cloud security adds extra protections and tools to focus on the vulnerabilities that come from Internet-facing services and shared environments, such as public clouds. It also tends to include a focus on centralizing security management and tooling. This centralization enables security teams to maintain visibility of information and information threats across distributed resources. Another aspect of cloud security is a collaboration with your cloud provider or third-party services. When using cloud-hosted resources and applications, you are often unable to fully control your environments since the infrastructure is typically managed for you. This means that cloud security practices must account for restricted control and put measures in place to limit accessibility and vulnerabilities stemming from contractors or vendors. Endpoint Security Endpoint security helps protect end-user endpoints such as laptops, desktops, smartphones, and tablets against cyberattacks. Organizations implement endpoint security to protect devices used for work purposes, including those connected to a local network and those using cloud resources. Endpoints connecting to corporate networks become a security vulnerability that can potentially allow malicious actors to breach the network. An endpoint is essentially a potential entry point that cybercriminals can and often exploit through various techniques, like malicious software malware installed on an endpoint device to obtain control of a system or exfiltrate data. An endpoint security solution examines processes, files, and network traffic on each endpoint for indicators of malicious activity. Once the tool detects a threat, it notifies the relevant users and can perform automated responses. For example, an endpoint detection and response EDR tool can automatically respond to the threat using predetermined rules. Endpoint security solutions can employ additional strategies to protect endpoints, such as data encryption in transit and at rest, web content filtering, and application control. Related content: Learn more in the detailed guide to endpoint security Edge Security In an increasingly connected world, edge security is becoming more important. Edge security refers to the measures taken to secure the edge of your network—the point where your network connects with the outside world. This could include your routers, firewalls, or other edge devices. Securing the network edge is crucial to prevent unauthorized access to your network and protect it from threats like cyber attacks or data breaches. This could involve measures like using secure network protocols, implementing robust firewalls, and regularly monitoring and analyzing your network traffic. Learn more in the detailed guide to edge security Cryptography Cryptography uses a practice called encryption to secure information by obscuring the contents. When information is encrypted, it is only accessible to users who have the correct encryption key. If users do not have this key, the information is unintelligible. Security teams can use encryption to protect information confidentiality and integrity throughout its life, including in storage and during transfer. However, once a user decrypts the data, it is vulnerable to theft, exposure, or modification. To encrypt information, security teams use tools such as encryption algorithms or technologies like blockchain. Encryption algorithms, like the advanced encryption standard AES , are more common since there is more support for these tools and less overhead for use. Incident response Incident response is a set of procedures and tools that you can use to identify, investigate, and respond to threats or damaging events. It eliminates or reduces damage caused to systems due to attacks, natural disasters, system failures, or human error. This damage includes any harm caused to information, such as loss or theft. A commonly used tool for incident response is an incident response plan IRP. IRPs outline the roles and responsibilities for responding to incidents. These plans also inform security policy, provide guidelines or procedures for action, and help ensure that insight gained from incidents is used to improve protective measures. Vulnerability management Vulnerability management is a practice meant to reduce inherent risks in an application or system. The idea behind this practice is to discover and patch vulnerabilities before issues are exposed or exploited. The fewer vulnerabilities a component or system has, the more secure your information and resources are. Vulnerability management practices rely on testing, auditing, and scanning to detect issues. These processes are often automated to ensure that components are evaluated to a specific standard and to ensure vulnerabilities are uncovered as quickly as possible. Another method that you can use is threat hunting , which involves investigating systems in real-time to identify signs of threats or to locate potential vulnerabilities. Learn more in the detailed guide to vulnerability assessment Disaster recovery Disaster recovery strategies protect your organization from loss or damage due to unforeseen events. For example, ransomware, natural disasters, or single points of failure. Disaster recovery strategies typically account for how you can recover information, how you can restore systems, and how you can resume operations. These strategies are often part of a business continuity management BCM plan, designed to enable organizations to maintain operations with minimal downtime.

Scanning handwritten medical notes to store in a digital repository. Electronic health records EHR. In addition to organizing medical data, HDR also integrates the information to enable analysis. The goal is to make patient care efficient and help derive insights to improve medical outcomes while protecting the security and privacy of healthcare data. Successfully implemented HDM can improve the quality and quantity of health data. For example, including more relevant variables and ensuring records are up-to-date, validated, and complete for all patients can help improve data quality and increase the quantity. Since more data requires more interpretation, the dataset can grow, and deriving insights can become a complex task for healthcare providers. HDM helps take control of this data. Related content: Learn more in the in-depth guide to Health Data Management Digital Forensics Digital forensics is the identification, collection, and analysis of electronic evidence. Almost every crime today has a digital forensic component, and digital forensic experts provide critical assistance to police investigations. Digital forensic data is often used in court proceedings. An important part of digital forensics is analyzing suspected cyberattacks to identify, mitigate, and eliminate cyberthreats. Digital forensics thus becomes an integral part of the incident response process. Digital forensics can also help provide critical information required by auditors, legal teams, and law enforcement after an attack. This role may be a stand-alone position or be included under the responsibilities of the vice president VP of security or the chief security officer CSO. The responsibilities of a CISO include managing: Security operations—includes real-time monitoring, analysis, and triage of threats.

First, look at the address line: it should have a little padlock at the beginning — this means the connection is encrypted. Second, review the look and feel of a website.
Pro tip: Use the Clario browser extension to automatically check sites for malicious content and notify you if they are safe to access. Strong passwords should contain at least 12 symbols and feature a mixture of letters upper and lower case , numbers, and special characters. A recent cybersecurity study showed that passwords under 10 characters could be cracked within an hour. However, those containing at least 12 characters will take about a year to break and 15-character passwords will withstand a millenium of brute-force attacks. Pro tip: To check if your passwords leaked, use the Clario Data breach monitor — just enter your email, and we will check all the associated accounts for breaches.
When you sign into your account with 2FA, you must not only enter the correct password, but also an additional code generated earlier or sent to your device.

Together, the three principles should guide organizations while assessing new technologies and scenarios. Types of Information Security When considering information security, there are many subtypes that you should know. These subtypes cover specific types of information, tools used to protect information and domains where information needs protection. Application security Application security strategies protect applications and application programming interfaces APIs. You can use these strategies to prevent, detect and correct bugs or other vulnerabilities in your applications. If not secured, application and API vulnerabilities can provide a gateway to your broader systems, putting your information at risk. Much of application security is based on specialized tools for application shielding, scanning and testing. These tools can help you identify vulnerabilities in applications and surrounding components. Once found, you can correct these vulnerabilities before applications are released or vulnerabilities are exploited. Application security applies to both applications you are using and those you may be developing since both need to be secured. Infrastructure security Infrastructure security strategies protect infrastructure components, including networks, servers, client devices, mobile devices, and data centers.
The growing connectivity between these, and other infrastructure components, puts information at risk without proper precautions. This risk is because connectivity extends vulnerabilities across your systems. If one part of your infrastructure fails or is compromised, all dependent components are also affected. Due to this, an important goal of infrastructure security is to minimize dependencies and isolate components while still allowing intercommunications. Cloud security Cloud security provides similar protections to application and infrastructure security but is focused on cloud or cloud-connected components and information. Cloud security adds extra protections and tools to focus on the vulnerabilities that come from Internet-facing services and shared environments, such as public clouds. It also tends to include a focus on centralizing security management and tooling.

Be careful what you post and where The internet does not have a delete key. Similarly, be careful about disclosing personal information about yourself online. For example, avoid disclosing your social security number, address or date of birth in social media bios. Be careful about where you display or submit your email address. Be careful who you meet online People you meet online are not always who they claim to be. Indeed, they may not even be real. Fake social media profiles are a popular way for hackers to groom unwary internet users and pick their cyber pockets. Apply the same caution in your online social life as you would for your in-person social life. This is particularly true with the rise of online dating scams in recent years. Double check online information Sadly, fake news, misinformation and disinformation are all present on the internet. If you read something you are unsure of, do your own research to establish the facts. Reliable websites will have references to the original information and source materials. Read our guide to spotting fake news here. Often, children can accidentally be a gateway for malicious actors to gain access to your digital systems. It is therefore important to teach your kids the essentials of staying safe online in order to protect your home network from any unwanted accidents. Here are 3 areas that you should cover: Digital Footprint Your digital footprint, what exists of you online after usage, is an important concept that children need to know about. Wider discussions can also come from this, such as sharing content online through social media, gaming accounts and emails. Make sure to clearly state what content is not allowed on the internet photos, address, phone numbers and middle names. Passwords Strong passwords are integral to modern cybersecurity measures today. Instructing children from a young age about the importance of strong passwords ones that consists of at least 12 characters and are a mixture of letters, numbers and symbols and their appropriate storage is one of the simplest ways to make the internet safer for your family. This is also why it can be very useful to have a password management system that can automatically fill in password credentials for different websites.
Blockchain cybersecurity Blockchain cybersecurity is a technology that relies on immutable transactional events. In blockchain technologies, distributed networks of users verify the authenticity of transactions and ensure that integrity is maintained. While these technologies are not yet widely used, some companies are beginning to incorporate blockchain into more solutions. Endpoint detection and response EDR EDR cybersecurity solutions enable you to monitor endpoint activity, identify suspicious activity, and automatically respond to threats. These solutions are intended to improve the visibility of endpoint devices and can be used to prevent threats from entering your networks or information from leaving. EDR solutions rely on continuous endpoint data collection, detection engines, and event logging. Extended Detection and Response XDR XDR is a collection of technologies that help security teams improve the effectiveness of their threat detection efforts and the speed of their investigation and response. XDR combines data from all layers of the IT environment, including networks, email, endpoints, IoT devices, cloud workloads, identity systems, and servers, and enriches the sources with threat intelligence to detect evasive, sophisticated threats. Since XDR solutions are cloud-based, organizations can implement them for heterogeneous, distributed IT environments. These turn-key solutions immediately provide value and help improve the productivity of security teams. These technologies enable you to scan configurations, compare protections to benchmarks, and ensure that security policies are applied uniformly. Often, CSPM solutions provide recommendations or guidelines for remediation that you can use to improve your security posture. A VPN creates a tunnel between the network and a remote user. It secures traffic flowing across the tunnel by encrypting it. VPN remote access connects one user to on-premises resources but does not provide visibility into cloud resources. Instead, it provides various network security tools as a cloud service. It means employees can use their devices to connect to the corporate network and access sensitive systems and confidential data. BYOD can improve the user experience, allowing employees to work using familiar devices from any location. It enables employees to use their devices to work remotely from home or while traveling. However, BYOD often leads to shadow IT, as IT staff have poor visibility if at all into these endpoints and cannot properly implement and maintain security measures. Organizations can protect against BYOD threats by employing application virtualization and endpoint security solutions to extend visibility and gain comprehensive security and management controls. Threat Intelligence Threat intelligence is information gathered from a range of sources about current or potential attacks against an organization. The information is analyzed, refined, and organized and then used to prevent and mitigate cybersecurity risks. The main purpose of threat intelligence is to show organizations the risks they face from external threats, such as zero-day threats and advanced persistent threats APTs. Threat intelligence includes in-depth information and context about specific threats, such as who are the threat actors, their capabilities and motivation, and the indicators of compromise IoCs. With this information, organizations can make informed decisions about how to defend against the most damaging attacks. Related content: Related content: Learn more in the in-depth guide to threat intelligence M Microsegmentation Microsegmentation is a security technique that splits a network into separate zones and uses policies to dictate how data and applications within those zones can be accessed and controlled. It enables security teams to dictate how applications or workloads can share data within a system, which direction the data may be shared, and whether security or other authentication measures are required. Unlike network segmentation, which typically requires hardware equipment and is geared to North-South traffic client-server data flows between data centers , microsegmentation relies on software and is tailored to East-West traffic, or server-to-server data flows between applications. Microsegmentation limits the type of traffic that can laterally traverse across the network, which can prevent common attack techniques such as lateral movement. It can be applied throughout the network, across both internal data center and cloud environments. ITAM is critical for information security, as it allows organizations to understand what assets they have, where they are located, and how they are being used. Proper ITAM can help organizations reduce risks and costs. It can enable them to identify unauthorized or outdated software that could pose a security risk, ensure compliance with software licensing agreements, and avoid overpaying for unused or underutilized assets. Related content: Learn more in the in-depth guide to IT asset management. Examples of Information Security in the Real World There are many ways to implement information security in your organization, depending on your size, available resources, and the type of information you need to secure. Below are three examples of how organizations implemented information security to meet their needs. The company wanted to gain access to more detailed reporting on events. Their old system only provided general information when threats were prevented, but the company wanted to know specifics about each event. This coverage included improved visibility into events and centralized DLP information into a single timeline for greater accessibility. The company sought to improve its ability to protect system information and more effectively achieve security goals. Through partnership, Grant Thornton created a data lake, serving as a central repository for their data and tooling. This centralization improved the efficiency of their operations and reduced the number of interfaces that analysts needed to access. Centralization also made it possible for the company to use advanced analytics, incorporating their newly aggregated data. They took this action to detect incidents more quickly, investigate activity more thoroughly, and respond to threats more effectively. These tools enable WSU to detect a wider range of threats, including dynamic or unknown threats, and to respond to those threats automatically. These tools provide important contextual information and timely alerts for threats that solutions cannot automatically manage so you can quickly take action and minimize damage. Information Security Certifications Another important aspect when implementing information security strategies is to ensure that your staff are properly trained to protect your information. One common method is through information security certifications. These certifications ensure that professionals meet a certain standard of expertise and are aware of best practices. Numerous certifications are available from both nonprofit and vendor organizations. It covers core knowledge related to IT security and is intended for entry-level professionals, such as junior auditors or penetration testers. This certification is offered through the Computing Technology Industry Association. Certified Information Systems Security Professional CISSP —ensures knowledge of eight information security domains, including communications, assessment and testing, and risk management. It is intended for senior-level professionals, such as security managers. Managed Security Service Providers MSSP Due to the global cybersecurity skills shortage, and the growing complexity of information security, many organizations are outsourcing their security operations. MSSPs can provide a wide range of services, including managed firewall, intrusion detection, virtual private network VPN , vulnerability scanning, and endpoint security services. They can also provide expert advice and guidance on how to improve the security posture. By utilizing an MSSP, organizations gain access to a team of security experts without the need to hire, train, and retain an in-house security team. It defines all component stages of the cyberattack lifecycle and provides information about techniques, behaviors, and tools involved in each stage of various attacks.
Program management—includes ensuring proactive maintenance of hardware and software through audits and upgrades. Investigations and forensics—includes collecting evidence, interacting with authorities, and ensuring that postmortems are performed. Governance—includes verifying at all security operations operate smoothly and serving as a mediator between leadership and security operations. What Is a Security Operations Center? SOCs serve as a unified base from which teams can detect, investigate, respond to, and recover from security threats or vulnerabilities. In particular, SOCs are designed to help organizations prevent and manage cybersecurity threats. The main idea behind a SOC is that centralized operations enable teams to more efficiently manage security by providing comprehensive visibility and control of systems and information. These centers combine security solutions and human expertise to perform or direct any tasks associated with digital security. These centers provide the highest level of control but have high upfront costs and can be challenging to staff due to difficulty recruiting staff with the right expertise. Internal SOCs are typically created by enterprise organizations with mature IT and security strategies. Virtual SOC—use managed, third-party services to provide coverage and expertise for operations. These centers are easy to set up, highly scalable, and require fewer upfront costs. The downsides are that organizations are reliant on vendors and have less visibility and control over their security. Virtual SOCs are often adopted by small to medium organizations, including those without in-house IT teams. Hybrid SOC—combine in-house teams with outsourced teams. These centers use managed services to supplement gaps in coverage or expertise. Hybrid SOCs can enable organizations to maintain a higher level of control and visibility without sacrificing security. The downside of these centers is that costs are often higher than virtual SOCs and coordination can be challenging. Common Information Security Risks In your daily operations, many risks can affect your system and information security. Some common risks to be aware of are included below. Social engineering attacks Social engineering involves using psychology to trick users into providing information or access to attackers. Phishing is one common type of social engineering, usually done through email. In phishing attacks, attackers pretend to be trustworthy or legitimate sources requesting information or warning users about a need to take action. For example, emails may ask users to confirm personal details or log in to their accounts via an included malicious link. If users comply, attackers can gain access to credentials or other sensitive information. Advanced persistent threats APT APTs are threats in which individuals or groups gain access to your systems and remain for an extended period. Attackers carry out these attacks to collect sensitive information over time or as the groundwork for future attacks. APT attacks are performed by organized groups that may be paid by competing nation-states, terrorist organizations, or industry rivals. Insider threats Insider threats are vulnerabilities created by individuals within your organization. In the case of accidental threats, employees may unintentionally share or expose information, download malware , or have their credentials stolen. With intentional threats, insiders intentionally damage, leak, or steal information for personal or professional gain. Cryptojacking Cryptojacking, also called crypto mining , is when attackers abuse your system resources to mine cryptocurrency. Attackers typically accomplish this by tricking users into downloading malware or when users open files with malicious scripts included. Some attacks are also performed locally when users visit sites that include mining scripts. Attackers can perform these attacks manually or through botnets, networks of compromised devices used to distribute request sources. The purpose of a DDoS attack is to prevent users from accessing services or to distract security teams while other attacks occur. Ransomware Ransomware attacks use malware to encrypt your data and hold it for ransom. Typically, attackers demand information, that some action be taken, or payment from an organization in exchange for decrypting data. Depending on the type of ransomware used, you may not be able to recover data that is encrypted. In these cases, you can only restore data by replacing infected systems with clean backups.

During these attacks, attackers intercept requests and responses to read the contents, manipulate the data, or redirect users. There are multiple types of MitM attacks, including: Session hijacking—in which attackers substitute their own IP for legitimate users to use their session and credentials to gain system access. IP spoofing—in which attackers imitate trusted sources to send malicious information to a system or request information back. Eavesdropping attacks—in which attackers collect information passed in communications between legitimate users and your systems.

Most strategies adopt some combination of the following technologies. Firewalls Firewalls are a layer of protection that you can apply to networks or applications. These tools enable you to filter traffic and report traffic data to monitoring and detection systems. Firewalls often use established lists of approved or unapproved traffic and policies determining the rate or volume of traffic allowed. This aggregation of data enables teams to detect threats more effectively, more effectively manage alerts, and provide better context for investigations. SIEM solutions are also useful for logging events that occur in a system or reporting on events and performance. You can then use this information to prove compliance or to optimize configurations. This includes categorizing data, backing up data, and monitoring how data is shared across and outside an organization. For example, you can use DLP solutions to scan outgoing emails to determine if sensitive information is being inappropriately shared. These tools evaluate traffic and alert on any instances that appear suspicious or malicious. These solutions respond to traffic that is identified as suspicious or malicious, blocking requests or ending user sessions. You can use IPS solutions to manage your network traffic according to defined security policies. User behavioral analytics UBA UBA solutions gather information on user activities and correlate those behaviors into a baseline. Solutions then use this baseline as a comparison against new behaviors to identify inconsistencies.
