Introduction to Shift Left Security

Overview

As businesses continue to rely more and more on technology to conduct their operations, the need for cybersecurity is becoming more and more prominent. An entire business could be destroyed by a single cyberattack, incurring a severe financial loss, harm to its reputation, and loss of the trust of its clients. Shifting security to the left can reduce these threats by making security more effective and unobtrusive. 

Security is intended to be incorporated into all phases of the software development lifecycle, from planning and design to testing and deployment, according to a strategy known as “shift left security.” By doing this, security is integrated into the development process from the beginning rather than being added as an afterthought. 

Shift Left Security aims to find and fix security problems as early as feasible in the development cycle. Since resolving issues later in the development cycle is usually more expensive, this helps to lower the cost of fixing security vulnerabilities. Also, as developers are urged to include security in their work, it might aid in raising the caliber of the software being created. 

Process for Implementing Shift Left Security 

1. Identify security risks and vulnerabilities- Identification of potential threats and vulnerabilities is the first step in putting shift-left security into practice. A security analysis of the program or application under development can be done to achieve this. 

2. Identify security weaknesses and threats- 

Identifying potential security risks and vulnerabilities is the first step in implementing shift-left security. A security analysis of the program or application under development can be done to achieve this. 

3. Include security procedures in the creation process- 

After identifying security risks and vulnerabilities, the next step is integrating security practices into the development process. This can require implementing security precautions and controls, including access restrictions, logging, and encryption. 

4. Implement security testing and validation- 

DevOps teams should use security testing and validation to find security flaws sooner in software development. This can involve using human testing procedures, automated security testing technologies, and validation by security professionals. 

5. Collaborate with different teams- 

Collaboration across several teams participating in the software development process is necessary for shift left security. DevOps teams should collaborate with developers, security professionals, and operations teams to find and fix security flaws as soon as feasible. 

6. Use automation- 

Shift Left Security can be streamlined with the aid of automation. To find and fix security vulnerabilities more effectively, DevOps teams should consider employing automated security testing tools and other automation tools. 

7. Implement continuous monitoring- 

Once the software has been installed, regularly checking for security flaws and dangers is crucial. DevOps teams should use continuous monitoring to find and address security flaws and events as they happen. 

Shift Left DevOps

Shift Left DevOps is a method for developing software that focuses on pushing tasks that would typically take place later in the process to the left or sooner. The phrase “shift left” describes moving actions that would ordinarily take place later in the process to earlier ones. 

Shift left DevOps involves performing tasks like testing, validating, and security earlier in the development cycle instead of waiting until the very end. This lessens the possibility of delays and added expenditures by enabling faster issue identification and resolution. 

The purpose of the shift left DevOps is to streamline and increase the effectiveness of the software development process. Teams can work more productively and efficiently, producing better software by detecting and resolving difficulties earlier. 

The DevOps methodology for developing software strongly emphasizes teamwork, integration, and automation between the development and operations teams. Including security technologies in the DevOps process is crucial since security is a crucial component of software development. In each step of the DevOps process, the following popular security tools are used: 

Planning Stage: 

Security tools are used to discover and evaluate potential security threats during planning. These tools consist of the following: 

• Threat modeling: This tool aids in locating the application’s potential security flaws and threats.
