Protecting against all attacks requires multiple steps, and implementing fundamental measures can guard against various threats. Here are examples of actions to safeguard networks:
-
Service and Protocol Management
- If a service or protocol is unnecessary, it should be deactivated. Attackers cannot exploit vulnerabilities in inactive services or protocols.
-
Firewall Implementation
- Firewalls, whether network-based or host-based, are effective defenses against various attacks. Network-based firewalls secure entire networks, while host-based firewalls protect individual systems.
While there is no single step to protect against all threats, several basic measures can significantly reduce the risk of various types of threats.
-
Keep Systems Updated
- Regularly apply patches released by vendors.
- Implement patch management for timely updates.
-
Disable Unneeded Services
- Remove or disable unnecessary services and protocols.
- Reduces vulnerability to potential attacks.
-
Intrusion Detection and Prevention
- Implement systems that observe and detect threats.
- Provide alerts and can block or stop attacks.
-
Anti-Malware Software
- Utilize up-to-date anti-malware software.
- Countermeasure against various types of malicious code.
