What is Cybersecurity?

Privilege escalation describes a situation where an attacker with some level of restricted access is able to, without authorization, elevate their privileges or access level. For example, a standard computer user may be able to exploit a vulnerability in the system to gain access to restricted data; or even become "root" and have full unrestricted access to a system. Penetration testers are ethical hackers who test the security of systems, networks and applications, seeking vulnerabilities that could be exploited by malicious actors.

Related to end-user training, digital hygiene or cyber hygiene is a fundamental principle relating to information security and, as the analogy with personal hygiene shows, is the equivalent of establishing simple routine measures to minimize the risks from cyber threats. The assumption is that good cyber hygiene practices can give networked users another layer of protection, reducing the risk that one vulnerable node will be used to either mount attacks or compromise another node or network, especially from common cyberattacks. Cyber hygiene should also not be mistaken for proactive cyber defence, a military term.

Attackers are increasingly choosing to deploy attacks on cyber-physical systems . Critical infrastructure sectors include energy production and transmission, water and wastewater, healthcare, and food and agriculture. In many countries, critical infrastructure is state-owned, while Cybersecurity in others, like the U.S., private industry owns and operates a much larger portion of it. CISA leads the Nation’s strategic and unified work to strengthen the security, resilience, and workforce of the cyber ecosystem to protect critical services and American way of life.

Vulnerability management is the cycle of identifying, remediating or mitigating vulnerabilities, especially in software and firmware. Vulnerability management is integral to computer security and network security. "Response" is necessarily defined by the assessed security requirements of an individual system and may cover the range from simple upgrade of protections to notification of legal authorities, counter-attacks, and the like. In some special cases, the complete destruction of the compromised system is favored, as it may happen that not all the compromised resources are detected.

A CSF Draft Profile, Cybersecurity Profile for Hybrid Satellite Networks Draft Annotated Outline is available for public comment through August 9, 2022. This Profile will consider the cybersecurity of all the interacting systems that form the HSN rather than the traditional approach of the government acquiring the entire satellite system that includes the satellite bus, payloads, and ground system. NISTIR 8286C,Staging Cybersecurity Risks for Enterprise Risk Management and Governance Oversight, has now been released as final. This report continues an in-depth discussion of the concepts introduced in NISTIR 8286,Integrating Cybersecurity and Enterprise Risk Management, and provides additional detail regarding the enterprise application of cybersecurity risk information.

Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative. The cloud computing bachelor's degree at WGU is 100% online, which means it works wherever you are. You can do your coursework at night after working at your full-time job, on weekends, while you're traveling the world or on vacation—it's entirely up to you. English Composition II introduces candidates to the types of research and writing that are valued in college and beyond.
