What Makes API Security a Key Focus in the
Cybersecurity Landscape?

2
Executive Summary- API security has emerged as a
critical focal point in the realm of
cybersecurity. Application Programming Interfaces
(APIs) play a pivotal role in modern software
development, enabling seamless data exchange and
enhancing business interactions. However, they
also present vulnerabilities that cybercriminals
can exploit, leading to data breaches and
financial losses. API security is a critical
concern that demands immediate attention. By
implementing these best practices, organizations
can reduce API security threats, protect
sensitive data, and remain compliant with
industry standards, ensuring the integrity and
reliability of their systems.
3
Application Programming Interfaces (APIs),
formally referred to as APIs, hold a prominent
position within contemporary software
development, having revolutionized the
functioning of web applications. They facilitate
seamless data and information exchange among
applications, containers, and microservices,
enabling developers to connect APIs with various
software and internal systems. This connection
aids businesses in interacting with clients and
making informed decisions. Despite their
numerous advantages, APIs are susceptible to
exploitation by hackers who seek to gain
unauthorized access to sensitive data, resulting
in data breaches, financial losses, and damage to
reputation. Therefore, it is imperative for
businesses to comprehend the API security threat
landscape and employ effective mitigation
strategies.
4
The pressing need to bolster API security
APIs play a pivotal role in enabling data
exchange among applications and systems,
streamlining complex tasks. However, as the
number of APIs continues to rise, organizations
often underestimate their vulnerabilities, making
them attractive targets for cyberattacks. A
survey in the Q1 Report of 2023 revealed a
staggering 400 increase in API-targeted attacks
over the past six months.
5
Security vulnerabilities within APIs compromise
critical systems, leading to unauthorized access
and data breaches, as exemplified by incidents
like the Twitter and Optus API breaches.
Cybercriminals can exploit these vulnerabilities
to launch various attacks, including
authentication attacks, distributed
denial-of-service attacks (DDoS), and malware
attacks. API security has emerged as a
significant concern for businesses, with another
report forecasting that API abuses will become
the most common attack vector leading to data
breaches by 2023, accounting for 50 of data
theft incidents, resulting in an annual cost of
75 billion to businesses.
6
Why API security remains a threat in 2023
Securing APIs has consistently posed a challenge
for most organizations, primarily due to
misconfigurations within APIs and the growing
number of cloud data breaches. API sprawl, the
uncontrolled proliferation of APIs across an
organization, has become a top threat to API
security. This issue is exacerbated by APIs often
being designed without robust security standards,
leading to insufficient authorization and
authentication, thereby exposing sensitive data
such as personally identifiable information (PII)
and other business-critical data.
7
API sprawl also gives rise to shadow and zombie
APIs, further complicating API security. Zombie
APIs are exposed, abandoned, outdated, or
forgotten APIs that, while once useful, have been
replaced by newer versions. As organizations
focus on building new products or features, these
neglected APIs remain in the application
environment, providing an entry point for threat
actors to access sensitive data. Shadow APIs, on
the other hand, are third-party APIs developed
without proper oversight, remaining untracked and
undocumented. Enterprises failing to safeguard
against shadow APIs introduce reliability issues,
data loss, compliance penalties, and increased
operational costs.
8
Furthermore, the advent of technologies like the
Internet of Things (IoT) adds complexity to
maintaining API security, as more remotely
accessible devices increase the risk of
unauthorized access and potential data breaches.
Additionally, generative AI algorithms can pose
security challenges, as hackers can exploit them
to detect vulnerabilities within APIs and launch
targeted attacks.

Best practices to enhance API security amidst
growing threats
API security is now a paramount concern for
organizations, necessitating a comprehensive
cybersecurity approach to mitigate threats and
vulnerabilities. Collaboration between developers
and security teams is crucial for implementing
best practices to bolster API security Discover
All APIs API discovery is essential for
uncovering modern API security threats like
zombie and shadow APIs. Organizations should
invest in automated API discovery tools to detect
every API endpoint, providing visibility into
live APIs, their locations, and functionalities.
10
Assess All APIs via Testing Traditional testing
methods are insufficient to address evolving API
security threats. Advanced security testing
methods like Static Application Security Testing
(SAST) should be adopted to identify
vulnerabilities within source code. Additionally,
consider using tools like Dynamic Application
Security Testing (DAST), Interactive Application
Security Testing (IAST), or Extended Detection
and Response (XDR) to enhance security
standards. Adopt a Zero Trust Security
Framework Implement user authorization and
authentication to reduce the attack surface.
Employ Zero Trust Architecture (ZTA) to segment
APIs into smaller units with their
authentication, authorization, and security
policies, providing greater control and enhanced
security.
11
API Posture Management Utilize API posture
management tools to detect, monitor, and mitigate
potential security threats from vulnerable APIs.
These tools conduct regular vulnerability
assessments, ensuring compliance with industry
regulations and internal policies. Implement API
Threat Prevention Recognize that API security is
an ongoing task. Employ proactive measures,
including specialized security solutions, threat
modeling, behavioral analysis, vulnerability
scanning, and incident response, to mitigate
potential API threats.
12
Conclusion In conclusion, the rise in API
adoption has exposed organizations to significant
security challenges. Securing APIs against
malicious actors, unauthorized access, and data
breaches is a paramount responsibility. This can
be achieved by adhering to practices such as
discovering all APIs, rigorous security testing,
adopting a Zero Trust approach, utilizing API
posture management tools, and implementing API
threat prevention measures. By following these
practices, organizations can reduce the API
threat surface, ensure the security of all APIs,
and maintain compliance with industry standards.
