If data is the lifeblood of your business, then network security is the gatekeeper that protects it from cyber-attacks. Adequate network security encompasses multiple layers of defenses: protection, detection, and response. Technical network security protects data stored within or transitioning between networks using tools like firewalls and encryption standards. It also includes physical security to prevent unauthorized access to networking components.

Encryption

A compromised key can give attackers access to sensitive information or steal network data. Network security uses encryption to keep these threats from being effective.

A robust network security strategy is critical to the success of your business. Without one, cyberattacks can wreak havoc and put your company’s operations at risk. From the loss of intellectual property to disruptions in customer service to damaging your reputation, a data breach can have far-reaching effects. A well-rounded network security strategy comprises three key focuses: protection, detection, and response. It is essential to keep in mind that the threat landscape is constantly evolving, so you must update your strategy accordingly. It can be done through continuous testing and training for your employees. Also, it is essential to have a backup plan for resolving any issues that arise. It is where a strong partner with experience in network security can help. They can provide the tools and resources to safeguard your business against threats.

Authentication

Protecting data from attackers requires authentication, which is a crucial component of network security. From requiring passwords to verify identity to using FIDO2 security keys or hardware OTP tokens to access devices, authentication ensures that only authorized users can access sensitive data. It’s also common for cybersecurity professionals to implement multifactor authentication, or MFA, for their employees and partners to access company applications and data. It can assist in lowering expensive breaches by providing an additional layer of security to stop hackers from guessing or breaking passwords. Other essential aspects of network security include firewalls, which control incoming and outgoing network traffic by applying predetermined rules. Firewalls can also incorporate intrusion prevention systems, which are software programs that scan and analyze network traffic to identify attacks and prevent them from occurring. It can help to eliminate attack windows and limit damage caused by malware, viruses, or worms. Moreover, it comes with anti virus and anti-malware programs that identify and eliminate dangerous software from networks.

Monitoring

Network security monitoring is a critical part of any company’s cybersecurity. Without it, the integrity of sensitive data is compromised, internal processes grind to a halt, and your business reputation suffers. The three primary functions of network security are authentication, encryption, and access control, but monitoring is also an important component. It includes collecting security data, storing it securely, and analyzing it to identify threats. It’s also necessary to have an escalation ladder in place so that when a threat is identified, the appropriate individuals are notified immediately.

Monitoring is also an excellent way to detect unanticipated traffic spikes or devices that connect to your network, which could be signs of a cyberattack. Many attacks result from users making simple mistakes, such as clicking on an unsafe email attachment or revealing their login credentials to phishing scammers. By keeping an eye on your network and educating your employees, you can help prevent these types of attacks from happening.

Access Control

Network access control is an integral part of network security. It limits access to system files and data based on the user’s credentials, location, and other attributes. It is frequently predicated on the least privilege principle, which holds that users need only to be granted the minimal level of access (permission) necessary for them to carry out their duties. It allows for greater visibility and helps mitigate risks associated with unauthorized actions by cybercriminals, such as ransomware. Network access control also helps to monitor the flow of information through a network infrastructure, which is especially critical in light of Bring Your Device (BYOD) policies and the increased use of IoT devices in the workplace. It can help ensure that all devices used for company business adhere to internal security policies, preventing malicious software from entering the system or accessing valuable or sensitive information. It can also prevent attackers from using rogue employee devices to distribute viruses and malware throughout the corporate network.
