Network security is any activity designed to protect the usability and integrity of your network and data.
- It comprise both hardware and software technologies
- It detects a variety of threats
- It stops them from entering or spreading on your network
- Effective network security manages access to the network
How is the network security process?
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.
How do you benefit from network security?
Every organization that wants to deliver the services that customers and employees demand must protect its network. Network security also helps you protect proprietary information from attack. Ultimately it protects your reputation.
But most importantly, when it comes to network security solutions, the big question that arises is – WHAT ALL SERVICES DO WE NEED FOR SECURING DATA OVER NETWORK? Right?? So we are here with the answer you need to know before taking any wrong step. When you are working on the internet or on any intranet, or over other connections like VPN etc. you can opt for the following services that fall under network and data security. Namely:
- Application security
- Access control
- Email security
- Behavioral analytics
- Data loss prevention
- Intrusion prevention systems
- Mobile device security
- Security information and event management
- Web security
- Wireless security
- Network segmentation
- Anti-virus and anti-malware software
Firewalls put up a barrier between your trusted internal network and non-trusted outside networks, such as the Internet. They use a set of defined rules to allow or block traffic. A firewall can be hardware, software, or both.
A virtual private network encrypts the connection from an endpoint to a network, often over the Internet. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.
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
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 non-compliant endpoint devices or give them only limited access. This process is network access control (NAC).
Email 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.
To detect abnormal network behavior, you must know what normal behavior looks like. Behavioral analytics tools automatically discern activities that deviate from the norm. Your security team can then better identify indicators of compromise that pose a potential problem and quickly remediate threats.
Data loss prevention
Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.
Intrusion prevention systems
An intrusion prevention system (IPS) scans network traffic to actively block attacks. It not only blocks malicious activity but also tracks the progression of suspect files and malware across the network to prevent the spread of outbreaks and reinfection.
Mobile device security
Mobile security automatically and remotely deletes your data on lost devices. Mobile security prevents you from losing your phone containing vital personal or business data. To prevent the loss of company or personal data, an excellent mobile security solution will be able to erase data stored in your phone. You need to control which devices can access your network. You will also need to configure their connections to keep network traffic private.
Security information and event management
SIEM products pull together the information that your security staff needs to identify and respond to threats. These products come in various forms, including physical and virtual appliances and server software.
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.
Wireless networks are not as secure as wired ones. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere, including the parking lot. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.
Software-defined segmentation puts network traffic into different classifications and makes enforcing security policies easier. Ideally, the classifications are based on endpoint identity, not mere IP addresses. You can assign access rights based on role, location, and more so that the right level of access is given to the right people and suspicious devices are contained and remediated.
Anti-virus and anti-malware software
These software are used for protection against malware, which includes spyware, ransomware, Trojans, worms, and viruses. Malware can also become very dangerous as it can infect a network and then remain calm for days or even weeks. These software handles this threat by scanning for malware entry and regularly tracks files afterward in order to detect anomalies, remove malware, and fix damage.
