Cybercriminals are always looking for the weakest link in a network to crack the security of your business, hack your systems, and get confidential information. Some hackers do it because they can – and enjoy – spreading malware and damaging systems and data, while others do it for bragging rights, or to demand ransom. Regardless of the reason, malicious attacks are a terrible experience for any computer user, organization, or businesses.
There are aspects of your computer network that create an accessible entry point for cybercriminals. Here are the top four aspects, left untreated, that could be damaging your network:
1. Misconfigured Firewalls
If your firewall isn’t configured properly, it becomes an open door for attackers. It’s extremely important to configure your firewall based on your business’s security requirements. If you’ve configured the firewall to allow all traffic, you’re able to use filters to block specific traffic. If you’ve configured the firewall to deny all traffic, filters will allow specific traffic through. Make sure you’re analyzing and monitoring traffic, in order to maintain maximum security.
your default wireless network name is changed as well. Make sure your password is strong enough to discourage hackers.
2. Unpatched Vulnerabilities
Security researchers continuously discover new vulnerabilities in operating systems and applications. When a vulnerability is found, a fix is developed and issued by the OS or application developer. If you don’t patch and install security-related patches, your network is vulnerable to malicious attacks.
3. Unsecured Wireless Access Points
If you have a wireless network and you’re not using encryption, you’re going to attract a lot of hackers. With open wireless hotspots, hackers can do anything on your network, it won’t be traced back to them; it’ll be traced back to your connection instead. To make your wireless network less appealing to hackers, enable proper encryption on your wireless access points, ensuring your default wireless network name is changed as well. Make sure your password is strong enough to discourage hackers.
4. Default and Overused Passwords
Many network devices and software applications include default passwords. Many users forget or ignore the requirement to change default passwords, or use very common passwords, which can be easily found published on the Internet. Make sure you’re changing all default passwords, otherwise, hackers can gain access to your network.
Performing Attack and Penetration Tests
It’s important to perform attack and penetration tests on a regular basis, identifying vulnerable points in the network and focusing on external and internal users. After you’ve identified these points, you’re able to fix issues and avoid attacks from external sources. In order to detect all the vulnerable points in your network, perform the test from internal and external perspectives.
