The Complete Guide to Application Security Software

In today’s rapidly evolving digital economy, getting application security right should be a top priority. It is a crucial part of the software development lifecycle. Application security is the science of defending your apps from malicious attacks by identifying and fixing coding issues. 

In order to secure their applications throughout the software development lifecycle, organizations today invest a lot of effort and money in information security technologies and processes. 

A major challenge for software engineers, security professionals, and DevOps personnel is establishing application security software as systems get more complex and hackers attempt more attacks at the application layer.

How can companies that create software make sure they have all the tools and procedures in place to handle the various threats to application security?

What role does application security play?

Applications continue to be the weakest security link, hence application security is essential. Leading industry research studies indicate that focusing on application flaws and software vulnerabilities is the most typical external attack strategy. Online apps are the most frequent hacker vector in breaches, according to Verizon’s 2022 Data Breach Investigations Report. 

The most frequent external attack vectors continue to include software and application vulnerabilities, as well as breaches in the software supply chain, according to Forrester’s 2022 State of Application Security Report.

Unfortunately, it seems that the majority of businesses are still spending money on their security against additional threat channels. Currently, the level of investment in particular areas of protection, such the network, is frequently out of proportion to the level of risk those regions currently carry given the threat environment.

According to the Ponemon Institute’s Increasing danger to Enterprise Applications Research Report, “investment in application security is not commensurate with the risk.” The study’s conclusions state that while “the level of risk to networks is much lower than the investment in network security,” “there is a significant gap between the level of application risk and what companies are spending to protect their applications.”

Important trends in application security

Application security is gaining importance due to the constant increase in app development. The source of these apps is an ever-growing body of code, both open source and custom, which can act as a breeding ground for flaws that, if not properly addressed with AppSec methods and technologies, constitute increasingly serious security concerns. In conclusion, both the attack surface and the risks are growing.

Perhaps the most recent instance is the widespread use of a critical remote code execution (RCE) vulnerability (CVE-2021-44228) in Apache’s Log4j software library that was discovered at the end of 2021. When it was discovered, Jen Easterly, the director of the US Cybersecurity and Infrastructure Security Agency (CISA), said:

“Log4j vulnerabilities present a significant and ongoing threat to businesses and governments everywhere… Since these are the most significant vulnerabilities I’ve come across in my career, collaboration between the public and private sectors is essential if we want to keep our networks secure.

Over a year later, the threat is still there. In a recent joint advisory, CISA and the FBI cautioned that malicious actors might still compromise federal networks by exploiting this vulnerability.

What steps make up the application security process?

Application security is often ensured using the procedure defined in the Cybersecurity Framework (CSF) published by the US National Institute of Standards and Technology. This process can be summed up as follows:

Identify security threats

Utilize the right tools and security tests to safeguard your code, apps, data, and systems. Detect involved using technologies to find hazards and vulnerabilities and alert you to them. When flaws, weaknesses, or threats are discovered, take the appropriate action to stop or lessen them.

Recover by fixing any issues and regaining your capacity for normal functioning

The application security process comprises putting techniques in place to spot novel or atypical code, evaluate whether it’s vulnerable, and fix flaws before they put you at risk of intrusion or attack. 

In order to find and fix vulnerabilities throughout the software development lifecycle and prevent unauthorized access to your apps, data, or source code, a number of security testing techniques and tools are utilized, as described below. 

Methods of application security testing

The aforementioned methodology, like any comprehensive application security plan, calls for evaluating and protecting a wide range of apps, the majority of which are mobile, Cloud-based, or web-based. Application security measures must be put in place for each category in order to cover them all, as they differ in how they happen. In general, they are as follows:

  • The goal of mobile application security is to assess the risk associated with applications that run on mobile phone and tablet operating systems, notably Android, iOS, and Windows Phone. Depending on the environments in which they run, it assesses apps for vulnerabilities and looks for problems that can arise as a result of user action. Testing is done by pretending to be a hacker or other hostile actor and trying to attack programs. Mobile apps are secured via penetration testing, static and dynamic analysis, and other techniques.
  • With a focus on access control, data security, infrastructure protection, logging and monitoring, incident response, vulnerability mitigation, and configuration analysis, cloud application security addresses the security of applications in cloud environments. There are numerous policies and procedures being implemented at this time.
  • Web application security comprises finding and fixing holes and flaws in application design as well as making sure security controls are included into websites to defend them from attacks. Throughout the entire software development lifecycle, application security tools and solutions like SAST (static application security testing), DAST (dynamic application security testing), IAST (interactive application security testing), SCA software composition analysis, penetration testing, and runtime application testing (RASP) are used to achieve this.
