Learning about cybersecurity is really important for anyone getting into Computer Science. With so much of our lives happening online, it helps to know some key terms. Here’s a simple list of must-know words for beginners:
Malware is short for malicious software. It includes any software that is made to harm computers, servers, or networks. Examples of malware include viruses, worms, and ransomware. In fact, Cybersecurity Ventures estimated that by 2021, ransomware damages could hit $20 billion worldwide!
Phishing is when cybercriminals try to trick people into giving away personal info. They pretend to be someone trustworthy in emails or messages. A report found over 220,000 new phishing sites in just one month of 2020, showing how big this issue is.
A firewall is like a wall that helps keep your trusted network safe from untrustworthy networks. It can be a physical device or software. Firewalls are very important for stopping unauthorized access to a private network. The global firewall market was estimated at $3.5 billion in 2020 and is expected to keep growing.
Encryption is when information is turned into a code to keep it safe from unauthorized access. The world of encryption is getting bigger, with expectations of growth from 7.5 billion by 2027.
An IDS checks network traffic to look for harmful activities or rule violations. It alerts you when it finds a possible threat but doesn’t act on it. That job usually belongs to an Intrusion Prevention System (IPS). The IDS market was predicted to reach $5.4 billion by 2023.
A vulnerability is a weak spot in a system that can be targeted by attackers. McAfee found over 18,000 vulnerabilities in just 2019, which shows how important it is to regularly check security.
A Distributed Denial of Service (DDoS) attack tries to take a website or service down by overwhelming it with too much traffic. In 2020, the number of DDoS attacks went up by 15%, affecting many areas like education and healthcare.
A zero-day exploit is an attack that happens the moment a vulnerability is found, before the software can fix it. Forrester believes that by 2025, 70% of companies will deal with a zero-day vulnerability incident.
Social engineering tricks people into making security mistakes or sharing private information by manipulating human behavior. IBM shared that around 95% of security breaches happen because of human error.
MFA adds extra security by requiring more than one way to verify your identity when logging into a system. This makes it much harder for attackers. Microsoft says MFA can block up to 99.9% of automated attacks.
Getting to know these key terms is super important for anyone starting in cybersecurity. As cyber threats keep changing, understanding the basics can help you protect against different risks.
