Wits University is excited to offer a cyber security course this autumn. This is an important and timely topic, as cyber crime continues to be a major problem globally. The aim of the course is to provide students with the knowledge and skills required to protect themselves from online threats and protect their data.

What is Cyber Security?

Cyber security is the practice of protecting information systems and networks from cyberattacks. Cybersecurity includes protecting users’ data, managing risk, and monitoring and responding to attacks. Cybersecurity can be divided into three main areas: digital defense, network defense, and data protection.

Digital Defense: Digital defense includes protecting the digital environment by defending against cyberattacks. This includes protecting computer systems, networks, and critical infrastructure from infiltration and damage.

Network Defense: Network defense encompasses the measures taken to protect networks from unauthorized access, misuse, or destruction. These measures may include firewalls, intrusion detection/prevention systems (IDS/IPS), user authentication and role-based access controls (RBAC), satellite imagery analysis for suspicious activity, and more.

Data Protection: Data protection encompasses the various measures taken to protect the confidentiality, integrity, and availability of data. Measures may include encryption of data at rest and in transit, data backup/disaster recovery plans, incident response procedures, data breach notification policies, and more.

Types of Cyber Attacks

Cyber attacks come in all shapes and sizes, but they all share one common goal: to take control of a computer or other electronic device.

There are three main types of cyber attacks: physical, logical, and cyber.

Physical cyberattacks involve accessing or damaging physical devices or systems. Logical cyberattacks involve manipulating data or systems to achieve a desired outcome. Cyberattacks are simply any type of attack that uses the internet or other electronic mediums to reach its target.

No matter the type of cyber attack, it’s important to be proactive and aware of the risks involved. The best way to protect yourself is by taking a comprehensive cyber security course from Wits University. This comprehensive course covers everything from protecting your personal data to detecting and preventing online fraud.

What to do if you’re hacked

If you’re unlucky enough to be the victim of a cyber attack, there are a few things you can do to protect yourself. Whether it’s your personal computer or your company’s network, following these guidelines will help keep you safe.

1. Immediately take steps to protect your identity and sensitive information. Delete any incriminating files, change your passwords, and delete all cookies that could contain personal information.

2. Educate yourself about cyber security threats and how to protect yourself from them. Stay up-to-date on the latest cyber security news and learn about common attacks and how to avoid them.

3. Install antivirus software and firewall software on your computers and devices. Make sure they’re up-to-date and configured properly.

4. If you become aware of a cyber attack in progress, don’t panic! Try to collect as much information as you can about the attack (including the IP address of the attacker), and contact your IT department or security experts for help.
