Data Security 101: Practical Ways to Protect Your Data

With data breaches becoming increasingly common, it’s more important than ever to be diligent about protecting your data. But what can you do to keep your information secure? In this article, we'll go through some doable actions you can take to safeguard your data in today's increasingly data-driven society.

What is Data Security?

Data security is protecting your data from unauthorised access or theft. It includes physical security measures to protect your data from being physically accessed or stolen, as well as logical security measures to protect your data from being accessed or used without your permission.

Data security is important because it helps to ensure that only authorised people can access and use your data. There are numerous ways to safeguard your data, including physical security measures like using secure storage devices, as well as logical security measures like,

• Encrypting your data
• Creating strong passwords
• Using two-factor authentication

You should implement physical and logical security measures to protect your data effectively. Doing so can ensure that your data is safe from unauthorised access and theft.

Types of Data Security

There are many types of data security, each with its advantages and disadvantages.

Encryption

This is the most well-known form of data security. Encryption involves converting data into a code that can only be decrypted with proper authorisation. This makes it very difficult for unauthorised users to access or use the data. 

Tokenisation

This is a newer form of data security that is becoming more popular. Tokenisation helps reduce the risk of data breaches by minimising the amount of sensitive data stored in a system and making it more difficult for unauthorised users to access the original data. It is commonly used for protecting payment card information, personal identification numbers (PINs), and other sensitive data.

Hashing

This is another form of encryption, but it is much simpler and less secure. Using a mathematical function, hashing converts data into a fixed-length code (hash). Constant output results from a constant input, so verifying that the data has not been tampered with is easy. However, hashes can be cracked with enough computing power and time.

Digital signatures

A digital signature is a technique used in data security to verify the authenticity and integrity of a digital document. It is essentially an electronic equivalent of a handwritten signature and provides proof that the document was created by a known sender and has not been altered in transit. Digital signatures use cryptographic algorithms to generate a unique code associated with the document and the sender. The recipient can use this code to ensure that the document has not been tampered with and came from the stated sender. Using digital signatures is a convenient and safe way to authenticate electronic communications and transactions.

Practical Steps to Secure Your Data  

• Keep your Operating System (OS) and software up-to-date. 

One of the most important things you can do to keep your data secure is to keep your operating system and applications up to date. Keeping everything up to date is critical for your own security because hackers are constantly devising new ways to exploit flaws in obsolete software. You can usually set your software to update automatically, but it’s a good idea to check for updates manually from time to time.  

• Use strong passwords and two-factor authentication. 

Another way to help protect your data is by using strong passwords and two-factor authentication whenever possible. Strong passwords are long, complex, and unique, making them difficult for hackers to guess. When logging into an account, Two-factor authentication enhances security by requiring you to enter a code from your phone or another device in addition to your password. This makes it much harder for someone who tries to steal your password to gain access to your accounts. 

• Encrypt your data. 

Encrypting your data is another great way to protect it from being accessed by unauthorised individuals. Even if someone does manage to get their hands on your data, they won’t be able to read it unless they have the essential key to decrypt it.

How to monitor and protect your online presence?

In the modern world, our online presence is more important than ever. With social media, online banking, and other services, we must take steps to protect our data when we are online. Here are a few practical ways to do just that. 

• Monitor your online activity. 

• Keep an eye on what information you're sharing online and with whom. Be careful about posting personal information or financial details. Identity thieves can use even something as innocuous as your birth date. 

• Protect your passwords. 

• Make sure your internet accounts have secure passwords and change them regularly. Do not use the same password for various accounts. If one account is compromised, all of your others are at risk.

Here are some tips to keep your password safe: 

• Use a strong password: 

• Use upper and lowercase letters, numbers, and symbols to create a password of at least 12 characters. 

• Avoid using personal information: 

• Don't use easily accessible information such as your name, address, or date of birth in your password. 

• Don't reuse passwords: 

• Use a unique password for each account to prevent a compromise of one account from affecting all of your accounts. 

• Enable two-factor authentication: 

• When available, use two-factor authentication to add an extra layer of security to your accounts. 

• Use a password manager: 

• A password manager can securely store your passwords and generate strong ones for you, making it easier to use unique passwords for all your accounts. 

• Be cautious of phishing scams: 

• Be careful of emails or links claiming to be from trustworthy sources that ask for your password. 

• Update your passwords regularly: 

• Regularly changing your passwords helps to reduce the risk of your accounts being compromised. 

• Limit access to your personal information. 

• Be careful about who you share your information with, online and offline. Consider whether you need to provide certain sensitive details, such as your phone number or bank account information.

Creating a Backup Plan for Your Data

Regarding data security, Making a backup strategy for your data is one of the most crucial things you can do.

This will ensure that if your primary data source is compromised, you have a secondary source to fall back on. There are several methods you may use to back up your data.

One option is to use an online backup service to store your data in the cloud and allow you to access it from anywhere. Another option is to use an external hard drive or USB drive to store your backups locally.

Whichever method you choose, it's important to ensure that your backups are stored safely and securely. You should also regularly test your backups to guarantee they are working properly.

Benefits of Data Security 

Data security is more important than ever as we increasingly rely on technology. Data security benefits include preventing breaches, deterring cyber-attacks, and protecting individuals' privacy. Cyber-attacks are another serious threat faced by businesses today. These attacks can disable systems and encroach sensitive information. Data breaches can cause massive financial damage to companies and their reputation, which can be difficult to recover from. In 2018, the average data breach cost was $3.86 million, and all breaches that year were $654 billion. Companies can protect themselves from these unfortunate events by implementing data security measures. Data security makes it more difficult for hackers to access critical information, which can help deter these assaults.

Conclusion

Data security is essential in this digital age, and it's vital to stay competitive by safeguarding data. We hope the tips you've learned about data security have been informative and useful.
