Pros and cons of firewall

A firewall is a simple term, is a piece of hardware or software that protects a single computer or a network of computers. This security is achieved through the use of software, hardware, or a combination of the two to allow only approved traffic and block all unauthorized user from accessing private system and networks. You can check out the pros and cons of firewall her in this article to know more about it. 

Pros of firewall | Advantages of firewall:

  • A firewall prevents hackers and remote access.
  • It protects data.
  • Better security and network monitoring features
  • It ensures better privacy and security.
  • Help VOIP phone reliability.
  • It protects from trojans.
  • Allow for more advanced network functionality.
  • A network-based firewall, such as a router, can protect numerous systems, but an OS-based firewall can only protect single computers.

Cons of firewall | Disadvantages of firewall:

  • Depending on the level of sophistication necessary, installing a firewall might be pricey.
  • This is harmed because each packet must be authenticated before being let into the network.
  • Need for professionals to manage.
  • There are a few limitations in a firewall like its inability to prevent virus and malware attacks for which separate applications would be required at the individual system level.
  • Firewall maintenance and up-gradation require extra manpower and resources.
  • Can slow down your internet speeds.
  • A network-level firewall might bring in a false sense of security in employees and make them slacken on securing individual systems. Companies must ensure that all employees are aware of the notion of a firewall, as well as its necessity for information security and their responsibilities.

VPN vs Firewall

What is VPN?

The term VPN refers to a virtual private network. It's a kind of private network that's also virtual. We can use a public network as a private network since VPN is a technique for handling encryption, integrity protection, and certification or authentication. On a public network, it gives the appearance of a private network.

What is a firewall?

A firewall is a network security device that examines all incoming and outgoing network traffic. Based on a defined set of security criteria, firewall devices whether to accept or prohibits traffic. They serve as the network security system's initial line of defense, forming a barrier between secured and controlled internal networks.

VPN vs firewall | Difference between VPN and Firewall:

  • A VPN can't create security rules or block data packets from entering your machine. If there is a problem connecting to the VPN server, some VPN clients may have a killswitch feature that disables internet access. However, this merely protects you from accidentally exposing your true IP address.
  • A firewall lets you configure the way your computer communicates with the internet by setting your own set of security rules, which prevents malicious traffic from entering your device.
  • VPN encrypts your internet connection, ensuring that no one can track your online activities or steal sensitive information like account credentials or credit card numbers.
  • While a firewall cannot assist you to avoid geographical restrictions so that you can access any content online even if it is not available in your country, a VPN can. Only websites that can be visited from your computer are restricted by the firewall.

Benefits of firewall

 Let us check the Benefits of a firewall which are listed below:

  • A firewall prevents hackers and remote access.
  • It reduces better privacy and security.
  • It protects data.
  • It protects from trojans.
  • A network-based firewall, like a router, can offer protection to multiple systems while an OS-based firewall can protect individual systems.
  • Only need to ensure the firewall is void vulnerabilities to secure assuming no backdoor exists.
  • All internal hosts' DNS information can be blocked or hidden.
  • A firewall offers a method to enforce the network policy of an organization.
  • Provides integrated perimeter security.
  • Simplify audit requirements with instant user identification.
  • User identity-based decision-making prevents errors associated with IP address-based policies. Secure dynamic IP environments like WiFi and instances where users share the endpoints.
  • A firewall functions as a chock point all traffic in and out must pass through this single checkpoint.
  • A firewall separates your site's network from other networks or one section of your network from another section.

VPN vs VPS | Difference between VPN and VPS

VPN and VPS are very different tools for very different jobs. Both are hosting and one for securely connecting. So here this article gives the difference between VPN and VPS to better understand this topic.

What is VPN?

VPN stands for the virtual private network. It is a sort of network that is private but virtual. Because VPN is a mechanism for handling encryption, integrity protection, and certification or authentication, we can use a public network as a private network. It creates the illusion of a private network on a public network.

What is VPS?

VPS stands for Virtual private server, VPS is a virtual dedicated server. The VPS, which uses virtualization software to partition physical into multiple virtual servers each having the ability to run its own operating system and applications. The customer who purchases the VPS will have root or admin-level access, on which he can install and configure any software as well.

VPN vs VPS  | Difference between VPN and VPS:

  • VPN can help both individuals and businesses protect their privacy and change their apparent online location, VPS is a must to businesses since it provides affordable, powerful server hosting to support websites, advanced applications, and similar functions.
  • VPNs, unlike VPSs, do not normally host websites or applications. VPN alters the way your internet traffic is routed, allowing you to pretend to be in another location.
  • VPN is focused on and often designed around their security features such as tunneling, Ip masking, no logs, and kill switches, to name just a few. VPN may be vulnerable to a hack or government surveillance. A virtual private server (VPS) is mostly used for server hosting, not data security.
  • VPNs can change their user's IP addresses and regularly do so to get past geo-blocking. While the VPS typically cannot change the apparent location of the internet traffic they handle. You won't be able to circumvent geoblocks if your VPS is located in a geo-restricted country.
  • VPS is a cost-effective server to host with, while VPN is a service that safely privately connects you with the internet from various locations.

Difference between VRC and LRC

Definition of VRC:

VRC  stands fr vertical redundancy check, it can detect all signal bit errors. It can detect burst errors if each data unit is odd.VRC cannot detect errors where the total number of bit changes is even.

Definition of LRC:

LRC stands for Longitudinal redundancy check, It used parity to determine wheater a message has an error. LRC has sometimes called message parity. Each bit position has a parity bit.  LRC bit is calculated in the transmitter and appended at the end of the message as a redundant character.

Difference between VRC and LRC:

  • VRC stands for vertical redundancy check, while the LRC stands for Longitudinal redundancy check.
  • VRC is not capable of checking the burst error case of change of bits is even, while the LRC is two bits in data unit is damaged and also other data unit the same bits are damaged the same position, then it is not capable of detecting such kind of error.
  • VRC can detect single-bit errors, while the LRC can detect burst errors.
  • VRC is also known as a parity checker, while the LRC is also known as 2D parity checker.
  • VRC can check all single-bit errors but can check odd parity only in the case of a change of odd bits. LRC has the advantage over VRC in that it can check all burst errors.

CRC vs checksum

What is a checksum?

The checksum is the most commonly used tool for detecting data errors. This method of error detection is more reliable than other methods. A checksum generator is used and on the receiver side, a checksum checker is used.

What is CRC?

CRC stands for cyclic redundancy check and it is an error detection tool used by upper-layer protocols to detect errors. The polynomial generator is present on both the sender and receiver sides.

Difference between CRC and Checksum:

  • The checksum is not a thorough concept for detection and reporting of error, while the CRC is a thorough concept for detection and reporting of error.
  • The checksum is capable of detecting a single-bit change in the data, while the CRC is capable of detecting double digits errors.
  • The error can be easily computed in checksum while the CRC follows a complex computation method.
  • The checksum is the method that comes after the CRC method, while the CRC is the oldest method.
  • The checksum is based on the addition approach, while CRC is based on the hash approach.
  • CRC is widely used in analog transmission for data validation, while the checksum is widely used in data validation during the implementation of software.
  • The checksum can compute fewer number errors than CRC, while the CRC is too complex to computation, it can detect more errors.
Summary:
  • CRC is more thorough as opposed to the checksum in checking for error and reporting.
  • The checksum is the older of the two programs.
  • In comparison to checksum, CRC needs a more complex calculation.
  • The checksum detects single-bit data changes, while the CRC will search and detect double-digit errors.
  • Because of its more complex function, CRC can detect more errors than the checksum.
  • When implementing applications, checksums are often used for data validation.
  • In analog data transmission, a CRC is primarily used for data evaluation.
