When is Computer Security Day celebrated

Computer Security Day 2023: Hello friends, hope you are enjoying the special day by reading this information. Today’s era is the era of electronic devices. Today everyday electronic devices like smartphones, tablets and computers have their own importance in our lives. They make our work easier and they also make communication easier. #ComputerSecurityDay

Without them all our work remains incomplete. In a way, our life does not seem complete without them. With the advent of these things our life has become so easy and efficient.

But at the same time, these technologies have brought new concerns about the privacy and security of our lives. And for this reason, this day is celebrated to help provide more security to your online data.

Computer Security Day is celebrated every year on 30 November, this day is celebrated with the aim of encouraging the protection of personal information in computers. It was celebrated for the first time in the year 1988.

Why is Computer Security Day celebrated?

Celebrating Computer Security Day started in 1988. Computers were a common thing around that time, although they did not reach homes. But the 1980s were the initial phase of computer business and proliferation.

Hacking and viruses have been around since the early days of modern computers. At that time computers were used in banking, government offices and institutions.

Whose entire data was stored in computer servers, and its hacking directly meant leaking of valuable information. Therefore, computer security became an important concern at that time.

Along with the rapid development of problems like hacking and viruses, their side effects also became more visible due to their excessive use. And it became a simple matter that people’s data was at greater risk. And for this reason, providing online security has also become an important and a matter of concern these days.

computer literacy Along with this, this Computer Security Day is celebrated to increase awareness among the people. At that time, International Computer Security Day was started to raise awareness about computer security and since then till today International Computer Security Day is celebrated for this purpose.

How is Computer Security Day celebrated?

All of you on this day Update spyware and malware protection software. Keep in mind that if you are asked to update the software when you visit any website, never click on it by mistake.

If you are a company or business owner, then all your employees should be aware of all the computer security and necessary information. Privacy and software updates Ask to do it and pay attention to it yourself.

Your website or files and photos or any other important Data Make a backup of.

Secure the data you have on your computer or tablet or mobile.

If you did your son’s change password It has been many days so you must change it today.

and also your cloud data Keep it safe once too.

Whenever you are online, all your Always keep the password strong and updated regularly Keep doing.

Because this password protects you from all your personal data falling into wrong hands. If you do not have a good password, your data can be stolen at any time without you knowing.

Keep the password as complex as possible and difficult to guess. You must use letters as well as numbers and symbols in your password.

You must use both capital and small letters in letters. And try to keep the length of the password 10 words or more. Be careful not to write the mobile number.

Never use only one password to protect any online account. Because if someone knows the password of one of your accounts, then he can definitely hack or misuse the same password of all your other accounts also.

For this reason, create a strong password for your online presence or account and keep updating them regularly.

If it has been a long time since you changed your password, then take the time to change your password today. And remember the password you entered.

If you use the same or the same password in all your online accounts, then you may become vulnerable to hackers. Celebrate this day to change or update the passwords of all your accounts.

What is Data Encryption?

Encryption is the method by which data is converted into a type of code, so that no one can read or understand that data. Data Encryption Financial institutions and businesses use this encryption method to keep information secure.

Advanced Encryption Standard (AES)

AES is a symmetric encryption algorithm and one of the most secure. Governments use it to protect their data, and many software and hardware products also use it. This method uses a block cipher, which encrypts a fixed-sized block at a time, unlike other types of encryption, such as stream ciphers, which encrypt data bit by bit.

AES includes AES-128, AES-192, and AES-256. Major bits let you choose to encrypt and decrypt blocks in 128 bits, 192 bits, etc. There are separate rounds for each bit. A round is the process of converting plaintext into cipher text. For 128-bit, there are 10 rounds; 192-bit has 12 rounds; And 256-bit has 14 rounds.

Since AES is a symmetric key encryption, you must share the key with other individuals to access the encrypted data. If you do not share that data with other people in a secure way, they can decrypt that encrypted data.

Triple Data Encryption Standard (3DES)

Triple Data Encryption Standard is a block cipher. This is similar to the older method of encryption, the Data Encryption Standard, which uses 56-bit keys. However, 3DES is a symmetric-key encryption that uses three individual 56-bit keys.

This encrypts the data three times, meaning your 56-bit key becomes a 168-bit key. Since it encrypts the data three times, this method is much slower than others. 3DES uses shorter block lengths, so data is easier to decrypt and leak.

However, many people use this encryption method to keep financial institution and business information secure. This is slowly disappearing as more robust encryption methods are introduced.

Twofish

Twofish is a symmetric block cipher based on an earlier block cipher – Blowfish. Twofish has a block-bit size of 128-bits to 256-bits, and works well on smaller CPUs and hardware. Similar to AES, it applies rounds of encryption to convert plaintext into cipher text. However, the number of rounds in it is 16, which is different from AES.

Furthermore, this method offers considerable flexibility. You can choose for the key setup to be slow but the encryption process to be quick. Furthermore, this form of encryption is inconsistent and license-free, so you can use it without restrictions.

RSA

This asymmetric algorithm is named after Ron Rivest, Len Adelman and Adi Shamir. It uses public-key cryptography to share data over unsecured networks. There are two keys: one public and one private. The public key is just as the name suggests: public.

Anyone can access it. However, the private key must be confidential. When using RSA cryptography, you need both keys to encrypt and decrypt the message. You use one key to encrypt your data and another to decrypt it.

According to search security, RSA is secure because it factors large integers which are the product of two prime numbers. Its key size is larger, which increases security. Most RSA keys are 1024-bits and 2048-bits. However, the longer key size is slower than other encryption methods.

There are several additional encryption methods available.

What is Computer Security Day?

Computer Security Day is celebrated every year on 30 November. The purpose of this day is to encourage security of personal information in computers. This day is especially celebrated to increase awareness about computer security and to protect the users from malicious and misuse.

Why is computer security important?

Computer security is very important because we all handle personal and private information using our computers, smartphones, and the Internet. Without computer security, our personal information may be at risk of attack by hackers or unauthorized persons. We can ensure our online security through increasing computer security awareness.

How is Computer Security Day celebrated?

People celebrate Computer Security Day to increase awareness in their computer and internet security. On this day people encourage users to update their security software, change passwords, and improve the security of their networks. Furthermore, companies and government organizations make their employees aware of the importance of security and advise them to follow security policies.

What is data encryption and why is it important?

Data encryption is a technique used to make data secure. In this technique, data is converted into a form that can be read and understood only by an organized key. The importance of data encryption lies in its secure operation, so that any unauthorized or inappropriate person can be prevented from accessing it. Data encryption is extremely important to keep the information handled by banks, financial institutions and businesses secure.

Why is encryption needed in computer security?

Encryption is needed in computer security because it is necessary to keep data secure. When you transmit data through the Internet, there is a risk that it can be read and understood by a layperson or a cracker. Encryption transforms data into a form that can only be read and understood by a special key, ensuring the security of the data. This keeps the data safe from unauthorized or unauthorized persons accessing your information.

What are the different types of data encryption?

Following are some important data encryption methods:

• Advanced Encryption Standard (AES): AES is a symmetric encryption algorithm and one of the most secure. This method encrypts a fixed size block at a time.
• Triple DES: Tri-DES is a symmetric encryption algorithm and uses three individual 56-bit keys. It encrypts the data three times making it extremely secure.
• Twofish: Twofish is a symmetric block cipher and the block-bit size is 128-bits to 256 bits. This method offers flexibility and is also license free, so it can be used without restrictions.
• RSA: It is an asymmetric encryption algorithm that consists of public and private keys. Because it has two keys, data can be operated in a secure manner.
