Database security—repelling a breach with defense-in-depth

The boldest attack in history ever! We all know the recent data breach that happened in July 2020, “Twitter Hack,” where hackers hacked high profile verified accounts and posted tweets from them.  

Do you know the reason why this mega data breach is happening? Who is the main culprit?

Poorly secured database that connects directly to the internet. The Popular NoSQL database is chronically under-protected. In contrast, I agree that it gives quick deployment, but sometimes it can break users into ignoring data security.  

The bitter truth is, it doesn’t matter what database you use. If you are not focusing on data security practices, you are inviting a breach. 

Let’s know how to beat back a breach with defense in depth for database security service at corpus Christi.

What is defense in depth?

Defense in depth is a security strategy during which professionals use many protection layers. It helps to stop direct attacks against the information system. If a hacker has access to a system, defense in depth minimizes negative impact and provides directors time to deploy updates to measures to stop a repeat of intrusion. 

How defense in depth works?

An approach to security can be applied to any level of IT systems. From the one computer accessing the web from house to the thousand user enterprise. Wide Area Network in defense in depth will considerably improve your security profile. 

Not any organization will ever be certainly protected by one layer of security. Wherever one door could be closed, the other is wide open, and hackers realize these mistakes very quickly. You can use a series of different defenses along with firewalls, detection systems, encryption solutions. You should effectively shut the gaps that are created by relying on single data security solutions. You can get protected security service at corpus Christi with fully encrypted data. 

What are the benefits of defense in depth?

Defense in depth is a multi-layered approach and often tailored to different levels of security. Not each of the qualities must be secure, and only the most business assets like proprietary and lead will be protected by foremost restricted settings. 

It is not possible to ensure the security of any single style application if any one system fails. It measures continuous vulnerability, and mistreatment of multiple systems leads to injury. The organization will make sure if one system fails, the other system continues to be protected itself.

If you are looking to create a defense in depth strategy for databases, you have policies and tools that can help. So let’s dive deep into these data security solutions. 

Authentication

It is the process of recognizing the user’s true identity. 

All users should authenticate themselves before gaining access to the database. Usually, it can be achieved by presenting the correct login credentials, that is, username and password. It is the first step of defense for your database. Here we have a few things to consider when setting up the authentication protocols.

Password Rules

Every year in online publications, the list of most used passwords is published. And every year, the same suspects top the charts. You should be strict for users to create unique passwords to avoid the pitfall of easily guessable passwords. Use long-phrase passwords that can be easy for humans to remember but impossible for hackers to guess. You can also use kerberos authentication for password protection.

Password management 

No matter how unique your passwords are, the truth is, no one can remember the number of passwords they create. So the only solution is a password manager. It allows users to follow your password rules while still able to use hard to crack passwords easily.  

Use encrypted channels

When logging into the database, use encrypted channels to transfer both username and password whenever possible. For example, Microsoft notes that using windows authentication is the best practice as using SQL server security sends the encrypted password but not the username. And username to be generic it’s one more hurdle hackers can easily overcome gaining access to databases by sniffing network communications. 

Grant Role

A role gives access to users certain privileges to view, edit, or perform other specified actions within the database. When setting up roles, you should follow the rule of least privileges. Administrative tasks should be given poorly, and giving permission to users to the ‘sysadmin’ role should be restricted. 

Permission assigned

Usually, a user’s permission is assigned to reflect the role they perform. 

Encryption of data

All data which is sensitive should be encrypted both at-rest and in-flight with strong, standard-based encryption. The encryption key should be stored within a centralized encryption manager. Users are only granted access to the keys if they are either authorized to view the unencrypted data or designated to manage the keys’ lifecycle.
