Security Proxy – A Comprehensive Guide to Improving Network Security

Trying to maintain a significant level of uptight security in a space where insecurity appears to be the order of the day is not an easy feat. Regardless, the struggle continues until this need is satisfied. So far, there have been diverse innovations to curb the high level of internet and network security and one of such innovation is the security proxy. 

But what exactly is a security proxy and what makes it stand out among other proxy variants? These are some of the details we will look into in the course of this article. Without further delay, let’s get right on to it!

What is a Security Proxy?

A security proxy is a proxy server that functions as a mediator between a user and specific servers to control network traffic. Its major purpose is targeted at improving security by implementing access supervision and filtering traffic according to fixed regulations and guidelines. 

When a user launches a request to gain entry into a specific server, the request is first relayed to the security proxy. This proxy evaluates the requests, confirms the user identity, and verifies whether that request action can be permitted according to the setup security regulations. If the request is verified to be allowed to pass through, the proxy instantly sends it across to the target server in the interest of the user. 

The same process applies to the feedback transmitted from the server to the user as the proxy intercepts the feedback and scrutinizes it based on security regulations. Afterwards, the proxy forwards the feedback to the user. 

Major Features That Highlight How Security Proxies Function

Now that we have acquainted ourselves with the concept of a security proxy, let us review some of the aspects that highlight how it operates. 

Verification and Authorization. Security proxies verify the user’s originality by employing username and passcode verification or virtual credentials. As soon as the user is verified, the proxy confirms if he meets all of the set conditions to push through with the request access.

Filtering Traffic. The proxy acts by reviewing traffic information in the network, inclusive of the request titles, request details, and feedback information. It can implement filters as well as guidelines to restrict or permit certain data that does not conform to the rules to prevent the transmission of malicious content.

Encoding and Decoding. Security proxies take care of the encoding and decoding tasks of network traffic to guarantee information privacy. It usually employs the likes of a secure socket layer and transport layer security protocol to launch secure contact between the users and the proxies and also the proxies and the server to be accessed. 

Load Stabilizing and Performance Improvement. Excluding the security quality, many security proxies additionally provide load stabilization capacities. They disperse inbound user requests to diverse servers to boost resource use and enhance processing time. By rationally directing this traffic, they can guarantee that no single server is swamped and can take care of the inbound request effectively.

Types of Security Proxies

There are different categories of security proxies focused on protecting diverse areas of network traffic. Let’s take a look.

• Web Application Firewalls

This category of security proxy focuses attention on securing applications from diverse attacks like malicious script injection, and SQL code manipulation, among others. They review HTTP-based traffic,  filter these invasive requests, and also offer an extra layer of security to these web-based apps. 

• Reverse Proxies

This category of proxy functions as a mediator between users and specific servers mainly specialized in transmitting inbound user requests to diverse background servers. They also offer load stabilization, data storage, and SSL termination assistance.  This proxy can help to improve the level of security by concealing private server information and safeguarding it from DDoS invasion. 

• SSL and TLS Security Proxies

These variants of security proxies help to handle SSL and TLS encoding and decoding procedures. They break off the proxy contact from users, decode existing traffic, and re-encode it before transmitting it to background servers. They help to ease the stress of encoding and decoding from servers and guarantee secure contact.

• API Proxies

These proxies function as mediators between users and background APIs, offering secure supervision over API permissions. They implement verification and authorization guidelines and also assist in filtering traffic and information review to safeguard APIs from misuse and odious activities. 

Disadvantages of Utilizing Security Proxies

While this proxy can be quite beneficial to individuals and firms, it can pose certain challenges as well. Let’s review some of these setbacks associated with the use of security proxies. 

• Speed hitches: The use of security proxies can adversely affect overall performance by causing low processing time. This is due to the extra time that the proxy may require to perform its review and filtering functions. This impact can be felt mostly when there is an increased level of traffic to be handled.
• Security delusion: Although security proxies offer an added advantage to network security, depending on them entirely can become a thing of delusion or what is tagged as a “false sense of security.” It is recommended that firms do not solely depend on security proxies as they can double it up with the likes of firewalls, invasion detection tools, and others.
• Set-up complication: Security proxies perform quite a heavy task compared to many other proxies and this also implies a heavy configuration process. The inaccurate set-up of these proxies due to their complexity can cause them to malfunction and carry out tasks wrongly. 
• Limited compatibility: Some security proxies do not function well with a vast variety of applications and software. This can become an issue if such a proxy is adopted in a complicated network area that demands the use of specific applications that they are not quite adaptable to. 

Factors to Consider Before Implementing a Security Proxy

The idea of security proxies providing a significant level of protection to network traffic strikes as tempting to many, especially firms. However, there are many things that you may need to consider before you decide to implement such a proxy variant for better security of your network traffic. Let us explore some of these factors.

• It is very crucial that you first review the network settings and system to be certain that it can adapt well to the security proxy that you intend to implement. This will assist you in going for the perfect choice to maximize the benefits that come with utilizing them. 
• Another important aspect you may need to consider is the performance effect of these proxies. If you are dealing with a work environment with traffic overload, you may need to ensure that the proxy can take care of the expected tasks without experiencing an obvious change in speed. 
• Also, you must review the security requirements of the firm that intends to implement these proxies. Knowing the exact kinds of invasion that the firm is attempting to shield itself against will allow it to make the right choice of security proxy to implement. 
• A review of the flexible nature of the security proxy is also an excellent idea. This will help to ascertain how well the proxy can deal with all the changes that may come in terms of the volume of network traffic and also developing security necessities and attacks. 
• Taking the step to review the reliability and supportive nature of the security proxy provider will also help to influence your proxy implementation. It is important to find out how dependable your proxy provider is in case of future updates and modifications.
• Ensure to review the financial effect of the intended security proxy to be implemented to be sure that it aligns with the expected budget. These cost reviews must include the current and anticipated cost of subsequent maintenance, among others. 

Wrap Up

Security proxies function as a gatekeeper, scrutinizing and supervising requests transmitted through a network. This action helps to shield the central servers from unwanted content and access, invasion as well and possible susceptibility. They offer an extra layer of protection and management, enabling firms to secure their network applications and settings. 

The benefits of implementing a security proxy are numerous and while you may have some reservations based on the probable setbacks that you may incur, it is vital that remember that there is no technological perfection in existence. The setbacks are outlined for you to implement with caution and set things in place to tackle any vulnerability that may arise. In all, security proxies are your go-to, especially for firms, to achieve an uptight security proxy remedy and improved network protection.
