Don’t Miss The Best Ways To Protect Networks From Ransomware!

Although it seems that new attacks have slowed in the past half-year, ransomware is still a prominent threat to business network security. The worst thing any company could do during this period of apparent dormancy is to relax its IT network security efforts and make itself vulnerable to a surprise attack.

To stay secure and reduce the possibility of falling victim to ransomware, companies should instead be using this time to improve network monitoring and implement the most effective techniques to prevent an attack in the future.

1. Anti-Everything Protection

The first line of defense against any kind of a malicious attack involves using the very basics of network security: anti-virus software, anti-malware protection, and anti-spam filters. Utilize the most advanced, updated anti-virus protection that can recognize both signature and behavior-based threats. Detect and filter out threats as they enter the system.

Additionally, beef up network monitoring by configuring firewalls and network folders to detect ARP-spoofing and filename spoofing. Assign packet-filtering rules and reject questionable packets.

2. Configure Segmented Networks

When configuring networks, divide them into subnets by department, server, location, or other groups. Connect the subgroups by a gateway and apply secondary IT network security features to the various subgroups. Should one subgroup on the network become infected, it will be possible to isolate it through the gateway and protect other subgroups from being affected.

3. Secure Network Configurations with Firewalls

Safely share internet connections throughout the network by configuring a NAT (Network Access Translation) proxy server with secure firewalls.

Prevent employees and other users from connecting their personal devices to gain internet access from the company LAN and block all networks and IP addresses known to be malicious.

Create access rules for system gateways, close any unused ports, and use port forwarding to provide certain access by external networks.

4. Restricted Access Policies

Control access throughout the company by developing IT network security access policies that restrict unnecessary access. Keep access levels as low as possible while still providing necessary access to shared resources. Control resources by providing read-only access unless write-access is essential.

Disable all unused services and only provide access to users who require it to complete their work. The less open access to the network there is, the higher the levels of network security will be.

5. Strong Password Generation and Certificate Policies

In addition to developing effective network monitoring and access control policies, companies must also protect their networks by requiring strong passwords and key-based authentication with VPN and SSH certificates. Passwords should require upper and lowercase letters, numbers, and special symbols, and be 8 or more characters.

Protecting company networks from ransomware attacks is a never-ending process. Even though the number of attacks on business systems may be slowed for the moment, companies must continue their IT network security efforts in preparation for the next wave.

The hackers developing these malicious programs are always working on their ability to breach current network security measures. Using effective network monitoring and implementation of the best security practices, companies must stay one step ahead of upcoming threats!
