Threat Prevention
Identify Threats
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.
Preventing Threats
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.
