Top 8 Tips To Ensure Database Security

Database Security

Nowadays, your customer data is one of the most important assets you have. 

This is why marketing intelligence is crucial in your business. They gather and analyze every information mainly for confidential decision-making in the market. They place a product in a particular store to understand how customers respond to the new product.

However, one of the challenges that business owners face these days is cyberattacks and other security threats that significantly impact their businesses.

Fortunately, Information Technology (IT) services like Houston IT services provided by Accudata Systems and others offer cybersecurity support to protect your business from cyber-attacks.

Furthermore, here are the eight tips you can implement in your company’s data security strategy to ensure data integrity in your database.

1. Use Separate Database Servers

Some factors influence server architecture; these include protection, performance, confidentiality, availability, and reliability.

Although keeping all servers like web servers, application servers, and database servers in one place is efficient, you run the risk of losing everything all at once.

Because these servers can be susceptible to attacks by outsiders such as hackers, they can get access to the server, steal your data, or insert dangerous malware to gain remote access. 

To avoid this pitfall, you need to put additional measures such as keeping your database isolated. In addition, your servers should be on a separate physical machine and not connected to any other application.

2. Implement Data Encryption

Data encryption is essential in securing your database from malicious parties attempting to access your data. You may try to take multiple steps to ensure your database from all threats, but cybercriminals aim to be ahead of you all the time. 

This is why encrypting the data on your database is one of the best countermeasures. It ensures that your data is indecipherable and unreadable to outside hackers.

Also, it means your information remains safe even if external hackers get a hold of your data. Apart from that, encrypting your data also means you can save sensitive information with better peace of mind and lower the risk of a data breach.

3. Employ Secure User Authentication

Recently conducted research shows that 80% of data breaches could be attributed to compromised passwords. It only proves how creating a password isn’t an excellent countermeasure. Also, it’s mainly because most users tend to create weak passwords. 

In addition, inside breaches usually happen because of too many users with privileged access to the database. Fortunately, there are other security measures you can implement to ensure the security of your database. These measures include

  • Limiting the number of users with access to the database.
  • Using strong passwords and multi-factor authentication.
  • Automatically locking accounts with several failed logins.
  • Deactivating all former team member accounts.

4. Practice Continuous Monitoring

Data monitoring and being aware of data movement means you know which part of the database is accessed.  It also grants you what information has been handled, when, and by whom. This security measure is a great way to keep track of those who try to access a database that they shouldn’t. 

Keep in mind that the information your database holds is precious to the company. This is why it deserves your full attention.

Through regular monitoring, you’ll be alerted when a hacking attempt has been made, when a team member is doing suspicious activities, if an account is accessed from an unexpected device, and if users are sharing accounts.

5. Perform Data Masking

Data masking is a technique of creating a fake but realistic version of your business data. The goal is to protect sensitive information while providing valuable data to the public.

For example, instead of showing all the card information of users, you should only show them the last four digits. You should apply this data security technique to every sensitive data before displaying it to internal users. 

Data masking offers excellent advantages such as saving the organization from critical threats like data exfiltration, data loss, insider threats, and insecure interfaces.

This anonymization technique is also a great way to reduce data risk with cloud adoption and make your data useless to an attacker while preserving its inherent functional properties.

6. Establish Web Application And Database Firewalls

Firewalls are the first layer in your database security measures.  It’s protecting you against security threats by denying access to malicious traffic. It’ll only give access to those authorized applications and block any unwanted connection attempt from unknown sources. 

Apart from protecting your database with a firewall, you should also add a web application firewall. This is because a database firewall won’t stop Structured Query Language (SQL) injection attacks.

Also, these attacks may come from a permitted web application that enables attackers to delete or exfiltrate the data from your database.

There are three standard firewalls to secure your network, namely proxy server firewall, packet filter firewall, and stateful packet inspection.

7. Update Database Software Regularly

Old and outdated software is open to any security threats made by hackers and cybercriminals. Research shows that 95% of websites use obsolete software components. This indicates that many businesses let their networks vulnerable to attacks with outdated software. 

Keep in mind that software update is vital to your cyber security and digital safety. That’s why apart from using trusted database management software, you should make sure it’s updated regularly.  This helps you stay protected against external weaknesses and other security issues.

8. Stop Using Default Ports

In modern database security, default ports are somewhat considered a weakness. Cyber attackers usually use these ports in brute force attacks because of their common occurrence.

When default ports are not in use, they will try every combination of passwords and usernames to gain access. That’s why you should monitor all ports and investigate any incidents such as unexpected open ports. 

This is to make sure your ports are closed when you’re not using them. Most importantly, stop using default ports.

Conclusion

Protecting your database will save your company from future security issues and help your marketing intelligence execute a better data-driven marketing plan.

When the administrator of your company’s database is aware of the potential threats, you can discuss these eight best database security practices with them.  Thus, you’ll know what suitable security measures you could implement in your business.
