How to Prevent Network Attacks
There are many different ways to defend against network-related threats. Here are five of the most effective methods.
1. Install antivirus software.
One of the first lines of defense against malware and other viruses is to install antivirus software on all devices connected to a network (Roach & Watts, 2021). Antivirus software can detect and prevent malicious files from being installed on a system, and it should be updated regularly to include the latest definitions.
2. Create strong passwords.
Another essential step in protecting a network is to create strong passwords. Passwords should be at least eight characters long and include a mix of letters, numbers, and symbols. They should also not be easy to guess—for instance, the user’s name or the name of the company.
3. Enforce security policies.
A third way to reduce risk of attacks on a network is to enforce security policies. Security policies can help ensure that all devices on a network are protected against viruses and malware and that users are using strong passwords. These policies can also restrict access to some network regions and limit user privileges.
4. Use firewalls.
Firewalls are another essential tool in defending networks against security threats. A firewall can help prevent unauthorized access to a network by blocking incoming traffic from untrusted sources. Additionally, firewalls can be configured to allow only certain types of traffic, such as web traffic or email.
5. Monitor activity.
Finally, it’s important to monitor activity on the network. Tracking logs and other data enables suspicious activity to be identified quickly, allowing security personnel to take steps to investigate and mitigate potential threats.
