General cybersecurity, offensive cybersecurity, and defensive cybersecurity are now available as different tracks.

Cybersecurity Specialist

Cybersecurity experts implement a variety of security procedures designed to safeguard a company's computer networks and systems. They keep track of potential system flaws that hackers might exploit, assess them, and correct them.

This study has an impact on the creation and application of preventative and protective measures that deter or completely halt cyberattacks.

The defense track of the BSCS curriculum is made to help students develop their analytical abilities. One of them is applying analytical skills to multiple network contexts, such as the cloud or mobile devices. Digital forensic procedures and incident response are also covered in these courses.

Defensive Security

Defensive security is a subset of cybersecurity that aims to safeguard the organization in all situations, from a network analysis of the current network to designing a security plan to ensure the effectiveness of any security controls integrated, all the way up to full network infrastructure protection.

The antithesis of offensive security Is defensive security. These are the thieves' security guards in the field of offensive security. To maintain both digital and procedural security, defensive security specialists sit in a firm's office and create computer systems, networks, and company regulations.

Someone has to install the firewall for every person who tries to get past it. There are people who built the system against intrusion and who fix the detected bugs for every system that has to be cracked. Defensive security experts are individuals who build up systems to stop the intrusion, monitor those first systems and find any incursion that gets through and safeguard assets against prospective intrusion. Patch systems to stop the replication of an intrusion.

Forensic analysis and security science are two additional areas that defensive security experts can pursue that are less common in the offensive security community.
