Computer security,cybersecurity,digital security or information technology security is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure,theft of,or damage to hardware,software,or data,as well as from the disruption or misdirection of the services they provide.
A cybersecurity regulation comprises directives that safeguard information technology and computer systems with the purpose of forcing companies and organizations to protect their systems and information from cyberattacks like viruses,worms,Trojan horses,phishing,denial of service (DOS) attacks,unauthorized access and control system attacks. While cybersecurity regulations aim to minimize cyber risks and enhance protection,the uncertainty arising from frequent changes or new regulations can significantly impact organizational response strategies.
A supply chain attack is a cyber-attack that seeks to damage an organization by targeting less secure elements in the supply chain. A supply chain attack can occur in any industry,from the financial sector,oil industry,to a government sector. A supply chain attack can happen in software or hardware. Cybercriminals typically tamper with the manufacturing or distribution of a product by installing malware or hardware-based spying components. Symantec's 2019 Internet Security Threat Report states that supply chain attacks increased by 78 percent in 2018.

Deception technology is a category of cyber security defense mechanisms that provide early warning of potential cyber security attacks and alert organizations of unauthorized activity. Deception technology products can detect,analyze,and defend against zero-day and advanced attacks,often in real time. They are automated,accurate,and provide insight into malicious activity within internal networks which may be unseen by other types of cyber defense. Deception technology seeks to deceive an attacker,detect them,and then defeat them.

Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face,the risks they introduce and mitigating security best practices to guide their behavior. End users are considered the weakest link and the primary vulnerability within a network. Since end-users are a major vulnerability,technical means to improve security are not enough. Organizations could also seek to reduce the risk of the human element. This could be accomplished by providing security best practice guidance for end users' awareness of cyber security. Employees could be taught about common threats and how to avoid or mitigate them.
Ryuk is a type of ransomware known for targeting large,public-entity Microsoft Windows cybersystems. It typically encrypts data on an infected system,rendering the data inaccessible until a ransom is paid in untraceable bitcoin. Ryuk is believed to be used by two or more criminal groups,most likely Russian,who target organizations rather than individual consumers.

Log4Shell (CVE-2021-44228) is a zero-day vulnerability in Log4j,a popular Java logging framework,involving arbitrary code execution. The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation,of which Log4j is a project,by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021. Before an official CVE identifier was made available on 10 December 2021,the vulnerability circulated with the name "Log4Shell",given by Free Wortley of the LunaSec team,which was initially used to track the issue online. Apache gave Log4Shell a CVSS severity rating of 10,the highest available score. The exploit was simple to execute and is estimated to have had the potential to affect hundreds of millions of devices.
