Generally speaking, network security is defined as the policies and practices of putting in place protective measures to keep network infrastructure safe from trespassers and other illegal users as well as from modification, abuse, change, destruction, and unauthorized gathering and release of data. A combination of hardware devices, security software, and user understanding of security processes and tactics are required for the entire process.
The last part can include anything from staff who have been informed on correct security practices to specialists who have completed network security certification training.
Why is Network Security Needed?
So many elements of our lives have been digitized and are now available online. We utilize the internet to conduct financial transactions, interact with family and coworkers, make purchases, look for amusement, and conduct research, among many other things. In this day and age, so much of our personal information is stored online, including everything from birth dates to Social Security (or other identification numbers), health histories to credit histories, bank accounts to utility bills, among a slew of other things.
Hackers and fraudsters can access all of that data and conduct all of those transactions. The more the number of our lives we devote to the internet, the greater the chance of being compromised. Furthermore, the continued prominence of the Internet of Things (IoT) means an even greater reliance on wireless networks, which only serves to exacerbate the threat environment by providing thieves with additional pathways and opportunities to perpetrate fraudulent activity. There is far too much at stake in our personal and professional lives to take any chances with network security. So, what are the different types of network security?
What Are the Types of Network Security?
Security experts have access to a vast array of network security resources including tools, methods, and techniques, as well as best practices. Here’s a high-level overview of the situation:
Anti-virus, anti-malware, and anti-spyware software are examples of software resources for software security. These tools are provided as suites or as subscriptions, and they are updated constantly by the hosting vendor to keep up with the most recent threats and vulnerabilities. These tools keep an eye on your network, preventing attackers, malware, and viruses from entering.
Software
As an aside, opting for a security subscription rather than purchasing a security suite and installing it in-house is highly prudent. When it comes to dealing with the always-changing cyber security landscape, subscription providers/vendors are in a better position than the average person. Cyber threats and viruses appear to be appearing daily, and your software will not be able to protect you against threats that it does not yet know about. That is why it is preferable to delegate the heavy job to a subscription service provider.
Password Protection
This is a straightforward measure, but it is incredibly significant. Using strong passwords to protect systems, applications, and networks is a low-cost but effective strategy to keep systems, applications, and networks safe, and you don’t need to be a seasoned cybersecurity professional to put strong passwords into practice. In addition, when we talk about “strong” passwords, we don’t only mean obscure ones like “password” or “99999.”

Firewalls
If you imagine your network as a high-end nightclub, the firewall would be the bouncer, in charge of keeping undesirables out and keeping the good ones in. They filter traffic (both incoming and outgoing) according to established policies, preventing unwanted users from entering the network. Anyone who has attempted to work remotely but been denied access to their company’s primary systems due to a lack of proper authorization has firsthand knowledge of the effectiveness of a firewall.
Email Security Software
E-mail is a particularly weak spot in any network’s defenses. Cybercriminals enjoy sending fraudulent emails that appear to be contacted by reputable businesses and financial institutions. However, a single click on a link hidden in one of these bogus emails may be enough to corrupt your system. To accomplish this, email security software can not only filter out inbound threats but can also prohibit certain types of data from being transmitted outward.
Segmented Networks
This procedure classifies and separates traffic according to specified criteria that have been established. In particular, segmented networks are beneficial for restricting users to a certain area, specifically the one in which they need to accomplish their work while keeping these users away from material that is outside of their purview. By restricting users in this way, we can reduce the number of weak points in the network as a whole.
Network Security Jobs and Salaries
In tandem with the surge in cybercrime, there has been an unsurprising increase in the demand for network security professionals. Furthermore, not only are there many prospects, but the work security is good and the salary is generous. Here’s a look at some of the most popular cybersecurity jobs and their associated salaries:
- The salary of an information security manager ranges from $120,000 to $160,000.
- Cybersecurity Engineer salaries range from $53,000 to $185,000 per year.
- Application Security Engineer salaries range from $81,500 to $191,500 per year.
- Cybersecurity Analyst salaries range from $53,000 to $116,000 a year.
- Penetration Tester salaries range from $70,000 to $169,000 per year.
- Network Security Engineer salaries range from $58,000 to $168,000 per year.
Which are the Best Network Security Certifications?
Before you can make a fortune in the field of network security, you must first learn the necessary tools and abilities. It is at this point that network security training becomes necessary. It is not just the information necessary for these professions that network security certification courses provide, but they also provide you with a valuable certificate that demonstrates to prospective employers that you have the necessary qualifications.
