How anti-virus software and firewalls work to protect against cyber threats?

Anti-virus software and firewalls are two common tools used to protect against cyber threats.

Anti-virus software is designed to detect and remove malicious software, such as viruses, worms, and Trojan horses, from a computer or network. The software works by scanning files and programs on the computer or network for patterns that match known viruses and other malware. If a match is found, the software can quarantine or delete the infected file to prevent further damage. Many anti-virus programs also include real-time scanning to monitor for and prevent infections as they occur.

Firewalls, on the other hand, act as a barrier between a computer or network and the internet or other external networks. Firewalls can be hardware or software-based and work by examining incoming and outgoing network traffic and either allowing or blocking it based on pre-defined rules. For example, a firewall might be configured to block all incoming traffic from a specific IP address or to only allow traffic to certain ports. Firewalls can help prevent unauthorized access to a computer or network, as well as block incoming attacks, such as Distributed Denial of Service (DDoS) attacks.

Both anti-virus software and firewalls are important tools in a comprehensive cyber security strategy. However, it's important to keep in mind that they are not foolproof and should be used in combination with other security measures, such as strong passwords and regular software updates, to help protect against cyber threats.
