There are quite a few different networking security tools you can incorporate into your lineup of services. The following list is by no means exhaustive, but available security tools can  include:

  • Access control. This refers to controlling which users have access to the network or  especially sensitive sections of the network. Using security policies, you can restrict network  access to only recognized users and devices or grant limited access to noncompliant devices  or guest users. 
  • Antivirus and anti-malware software. Malware, or “malicious software,” is a common  form of cyber-attack that comes in many different shapes and sizes. Some variations work  quickly to delete files or corrupt data, while others can lie dormant for long periods of time  and quietly allow hackers a back door into your systems. The best antivirus software  will monitor network traffic in real time for malware, scan activity log files for signs of  suspicious behaviour or long-term patterns, and offer threat remediation capabilities. 
  • Application security. Each device and software product used within your networking  environment offers a potential way in for hackers. For this reason, it is important that all  programs be kept up-to-date and patched to prevent cyber attackers from exploiting  vulnerabilities to access sensitive data. Application security refers to the combination of  hardware, software, and best practices you use to monitor issues and close gaps in your  security coverage. 
  • Behavioural analytics. In order to identify abnormal behaviour, security support personnel  need to establish a baseline of what constitutes normal behaviour for a given customer’s  users, applications, and network. Behavioural analytics software is designed to help identify  common indicators of abnormal behaviour, which can often be a sign that a security breach  has occurred. By having a better sense of each customer’s baselines, MSPs can more quickly  spot problems and isolate threats. 
  • Data loss prevention. Data loss prevention (DLP) technologies are those that prevent an  organization’s employees from sharing valuable company information or sensitive data— whether unwittingly or with ill intent—outside the network. DLP technologies can prevent  actions that could potentially expose data to bad actors outside the networking environment,  such as uploading and downloading files, forwarding messages, or printing. 
  • Distributed denial of service prevention. Distributed denial of service (DDoS) attacks is becoming increasingly common. They function by overloading a network with one-sided  connection requests that eventually cause the network to crash. A DDoS prevention tool  scrubs incoming traffic to remove non legitimate traffic that could threaten your network, and  may consist of a hardware appliance that works to filter out traffic before it reaches your  firewalls. 
  • Email security. Email is an especially important factor to consider when implementing  networking security tools. Numerous threat vectors, like scams, phishing, malware, and  suspicious links, can be attached to or incorporated into emails. Because so many of these threats will often use elements of personal information in order to appear more convincing, it  is important to ensure an organization’s employees undergo sufficient security awareness  training to detect when an email is suspicious. Email security software works to filter out  incoming threats and can also be configured to prevent outgoing messages from sharing  certain forms of data. 
  • Firewalls. Firewalls are another common element of a network security model. They  essentially function as a gatekeeper between a network and the wider internet. Firewalls filter  incoming and, in some cases, outgoing traffic by comparing data packets against predefined  rules and policies, thereby preventing threats from accessing the network. 
  • Mobile device security. The vast majority of us have mobile devices that carry some form of  personal or sensitive data we would like to keep protected. This is a fact that hackers are  aware of and can easily take advantage of. Implementing mobile device security measures  can limit device access to a network, which is a necessary step to ensuring network traffic  stays private and doesn’t leak out through vulnerable mobile connections. 
  • Network Segmentation. Dividing and sorting network traffic based on certain classifications  streamlines the job for security support personnel when it comes to applying policies.  Segmented networks also make it easier to assign or deny authorization credentials for  employees, ensuring no one is accessing information they should not be. Segmentation also  helps to sequester potentially compromised devices or intrusions. 
  • Security information and event management. These security systems (called SIEMs)  combine host-based and network-based intrusion detection systems that combine real-time  network traffic monitoring with historical data log file scanning to provide administrators  with a comprehensive picture of all activity across the network. SIEMs are similar to  intrusion prevention systems (IPS), which scan network traffic for suspicious activity, policy  violations, unauthorized access, and other signs of potentially malicious behaviour in order to  actively block the attempted intrusions. An IPS can also log security events and send  notifications to the necessary players in the interest of keeping network administrators  informed. 
  • Intrusion Prevention System: An intrusion prevention system (IPS) is a form of network security that works to detect and  prevent identified threats. The IPS reports these events to system administrators and takes  preventative action, such as closing access points and configuring firewalls to prevent future attacks.

  • Demilitarized Zone :A demilitarized zone (DMZ) is a perimeter network that protects an organization’s internal local area network (LAN) from untrusted traffic. A common DMZ meaning is a sub-network that sits  between the public internet and private networks. 
  • Web security. Web security software serves a few purposes. First, it limits internet access for  employees, with the intention of preventing them from accessing sites that could contain  malware. It also blocks other web-based threats and works to protect a customer’s web  gateway.
