In the past few years, the world has advanced technologically in so many ways. Everyone is digitally more interconnected than ever before. Networking technologies have made us dependent. The majority of your personal, commercial, and confidential data is stored on both private and openly accessible networks. There is a constant threat to our data available on the internet, and these threats are not always easy to detect or prevent. In a time like this, being educated about cybersecurity norms and needs is essential. Cybersecurity certificate programs and other online resources are popular choices among individuals to educate themselves on these topics. The Stanford Advanced Cyber Security Certificate is a well-recommended choice that one can opt for. This way, they can protect private data, stay safe from cyber fraud, and simultaneously upskill.

What is Network Security?

Network Security is any activity or approach undertaken to secure data and resources against any potential threat or unauthorized access. It makes use of software as well as hardware technologies to protect proprietary information from attack. It implements all possible policies and controls to ensure the optimal solution for network defense is in place. With the help of network security, only authorized users can gain access to data.
Network security acts as a protective wall, safeguarding the integrity and usability of your data from malicious software, threats, and exploitation.
There are many types of Network Security Options.

Types of Network Security:

1. Anti-virus and anti-malware software

“Malware,” which stands for “malicious software,” includes viruses, adware, scareware, rogue software, viper, worms, ransomware, and spyware. These are also dangerous software that will contaminate a network and not act immediately. They harm and exploit any programmable device and infiltrate the network. Besides scanning malware upon entry, these anti-malware programs also continuously track files to find anomalies, remove malicious software, and fix damages.

2. Firewalls

As the name suggests, firewalls are a network security system that acts as a barrier. They create an obstruction between the trusted internal network and untrusted external networks, like the Internet. They control incoming and outgoing traffic and weed out traffic coming from unsecured or suspicious sources.

3. Email Security

Emails are highly prone to a security breach. Emails are stored as clear text, making them accessible to third parties like email providers. End-to-end encryption isn’t enabled by email companies like Gmail and Outlook, making information susceptible to disclosure. An email security app blocks attacks from malicious software and protects sensitive data.

4. VPN

A virtual private network (VPN) extends a private network across a public network. It encrypts the connection from an endpoint to a network, often over the Internet. This way, one can establish an unknown presence on a public network.

5. Wireless Security

Wireless networks are not as safe and secure as wired networks. Installing a wireless LAN can be highly unsafe when it comes to network and data. To prevent harmful software and threats from manifesting, one must install wireless security. Wireless Security will prevent unauthorized users from accessing your Wi-Fi and stealing data using your network. Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) are the most common types of Wi-Fi security.


6. Data Loss Prevention

While dealing with large amounts of information and organizations with many-tier teams, information is prone to data leaks. Data prevention software ensures that sensitive data is protected, detected, and blocked. It detects potential data breaches and prevents them.

7. Application Security

Application security is the process of developing, assessing, and analyzing the security features of applications to secure them against unauthorized access and threats. All software needs to be protected. Any application can contain loopholes or gaps that hackers can use to infiltrate your network. Application security works at building the hardware, software, and processes that are required to prevent this.

8. Mobile device security

The main target pursued by cybercriminals is mobile devices and apps. The majority of companies have corporate work, team-based applications, and private data on their employees’ mobile phones. It is necessary to control which devices can access the network. It becomes essential for one to configure all-important connections to keep network traffic private.

9. Web security

Web security or cybersecurity is one of the most important elements of network security. It means protecting data on web applications by detecting, analyzing, and eliminating cyber threats. It’s integral to Information Security. Cybersecurity is essential for blocking malicious threats from online websites and denying access to unauthorized applications.
