Securing a network can seem overwhelming. The world of Security can be complicated. Network security tools assist in securing your monitoring IT environment.
The more tools an InfoSec professional has to work with, the better they will be able to address the task at hand. Access to a wide range of computer network security software is only the start. Knowing how to put them to use is the essence of network protection.
New security threats seemingly appear daily. The progressive nature of these attacks requires dynamic multi-point security solutions. It is critical administrators quickly identify vulnerabilities to protect data security.
But first let’s cover the basics.
What is Network Security?
Network security is a term that describes the tools, tactics and security policies designed to monitor, prevent and respond to unauthorized network intrusion, while also protecting digital assets, including network traffic. Network security is any activity designed to protect the usability and integrity of your network and data.
- It includes both hardware and software technologies
- It targets a variety of threats
- It stops them from entering or spreading on your network
- Effective network security manages access to the network
How do I benefit from Network Security?
Network security exists to help your organization protect not only its sensitive information, but also its overall performance, reputation and even its ability to stay in business. Continued operational ability and an intact reputation are two key benefits of effective network security.Network security also helps you protect proprietary information from attack. Ultimately it protects your reputation.
How does Network Security work?
Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats.
In this post, we’ll address top network security :
- Intrusion prevention systems
- Security information and event management (SIEM)
1. Access control
Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).
Firewalls function much like gates that can be used to secure the borders between your network and the internet. Firewalls are used to manage network traffic, allowing authorized traffic through while blocking access to non-authorized traffic.
3. Anti-malware software
Malware, in the form of viruses, trojans, worms, keyloggers, spyware, etc. are designed to spread through computer systems and infect networks. Anti-malware tools are a kind of network security software designed to identify dangerous programs and prevent them from spreading.
4. Anomaly detection
It can be difficult to identify anomalies in your network without a baseline understanding of how that network should be operating. Network anomaly detection engines (ADE) allow you to analyze your network, so that when breaches occur, you’ll be alerted to them quickly enough to be able to respond.
5. Application security
Any software you use to run your business needs to be protected, whether your IT staff builds it or whether you buy it. Unfortunately, any application may contain holes, or vulnerabilities, that attackers can use to infiltrate your network. Application security encompasses the hardware, software, and processes you use to close those holes.
6. Data loss prevention (DLP)
Often, the weakest link in network security is the human element. DLP technologies and policies help protect staff and other users from misusing and possibly compromising sensitive data or allowing said data out of the network.
7. Email security
E-mail gateways are the number one threat vector for a security breach. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. An email security application blocks incoming attacks and controls outbound messages to prevent the loss of sensitive data.
8. Endpoint security
The business world is becoming increasingly bring your own device (BYOD), to the point where the distinction between personal and business computer devices is almost nonexistent. Unfortunately, sometimes the personal devices become targets when users rely on them to access business networks. Endpoint security adds a layer of defense between remote devices and business networks.
9. Intrusion prevention systems
An intrusion prevention system (IPS) scans network traffic to actively block attacks. Cisco Next-Generation IPS (NGIPS) appliances do this by correlating huge amounts of global threat intelligence to not only block malicious activity but also track the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.
10. Network segmentation
There are many kinds of network traffic, each associated with different security risks. Network segmentation allows you to grant the right access to the right traffic, while restricting traffic from suspicious sources.
11. Security information and event management (SIEM)
Sometimes simply pulling together the right information from so many different tools and resources can be prohibitively difficult — particularly when time is an issue. SIEM tools and software give responders the data they need to act quickly.
12. Web security
A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. “Web security” also refers to the steps you take to protect your own website.
13. Wireless security
Generally speaking, wireless networks are less secure than traditional networks. Thus, strict wireless security measures are necessary to ensure that threat actors aren’t gaining access.
14. Mobile device security
Cybercriminals are increasingly targeting mobile devices and apps. Within the next 3 years, 90 percent of IT organizations may support corporate applications on personal mobile devices. Of course, you need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.
