Modern business, government, and interpersonal communications are massively reliant upon computer systems and applications. Cybersecurity is more important than ever in the cultivation of secure government agencies, private lives, and business networks. There is a vast range of different cybersecurity fields. This article is a very brief guide to some of the most important aspects of cybersecurity, focusing on the fields that are especially important to businesses.
Almost all computer systems are networked—connected together as part of a local or worldwide web. Network security is a field dedicated to the ongoing development of safe network protocols. This can involve the creation of safe data encryption methods, firewalls, VPNs, and a whole host of other strategies. As the world becomes increasingly networked, the importance of network security grows. All companies should consult with an experienced network security expert if they do not have one as part of their IT team.
Staff training is one of the most important elements of commercial cybersecurity. A great many of the vulnerabilities displayed by computer networks are actually made worse due to human error. If cybersecurity experts are able to deliver adequate training to the staff that will be using a computer network, the chances of a disaster occurring fall drastically. Human factors that impact cybersecurity include vulnerability to social engineering, taking the bait during “phishing” attacks, and sharing data with unauthorized parties online. Cybersecurity experts work in conjunction with HR professionals to arrange training for all members of an organization.
Authentication is an immensely important area within cybersecurity. Making sure that only the right people can access restricted areas is immensely hard, as hackers and social engineers can usually crack basic password authentication systems. Due to this vulnerability, most organizations are beginning to implement multi-factor authentication plans. In order to access sensitive content, a staff member must be able to produce two or more kinds of authenticating data. This can include passwords, biometric authentication, or device authentication.
Almost all computing tasks are completed using applications. Applications need to be developed and audited so as to prevent them from being security liabilities. Poorly developed or audited applications can act as doorways to an organization’s sensitive data. Therefore, application security is now considered to be an essential field.
Critical Infrastructure Security
Critical infrastructure security protocols protect digital elements that underpin the operation abilities of an organization. Every organization has some critical infrastructure that relies upon digital security—even governments. The United States of America has its own critical infrastructure security organization dedicated to the protection of critical systems. Critical infrastructure systems can be harmed by hacking attempts. When Russian hackers disrupted Ukraine’s power grid in 2016 and 2019, critical infrastructure cybersecurity defenses were breached. Governments use critical infrastructure cybersecurity protocols in an attempt to prevent incidents like the Ukraine power grid hack from occurring again.
On a smaller scale, companies might develop critical infrastructure security protocols in order to protect their financial and operational sectors.
