What makes API security an emerging challenge in
cybersecurity?

APIs, or application programming interfaces, play
an important role in modern software development.
They transformed the way web applications work by
making it easier for applications, containers,
and microservices to communicate data and
information. APIs can be linked by developers to
numerous software or other internal systems,
allowing businesses to engage with their clients
and make informed decisions. Despite the
numerous advantages, hackers can use API
weaknesses to obtain unauthorized access to
sensitive data, resulting in data breaches,
financial losses, and reputational harm.
Businesses must therefore understand the API
security threat environment and look for the most
effective mitigation strategies.

The urgent need to enhance API security
APIs facilitate data transfers between
applications and systems and aid in the smooth
execution of complex activities. However, as the
average number of APIs increases, corporations
frequently ignore their vulnerabilities, making
them an ideal target for hackers. According to
the findings of the State of API Security Q1
Report 2023 survey, attacks on APIs have surged
400 in the last six months.
4
API security flaws damage important systems,
resulting in unauthorized access and data
breaches such as the Twitter and Optus API hacks.
Cybercriminals can use the vulnerabilities to
perform a variety of attacks, including
authentication attacks, distributed
denial-of-service (DDoS) attacks, and malware
attacks. API security has emerged as a serious
corporate issue, with another analysis revealing
that by 2023, API abuses will be the most common
attack vector-producing data breaches, with
unsafe APIs accounting for 50 of data theft
occurrences. Due to this, protecting data has
become a top priority for businesses, which may
cost them 75 billion annually.
5
Why is API security still a concern in 2023?
Securing APIs has always been a difficult problem
for most organizations, owing to API
misconfigurations and the surge in cloud data
breaches. As the security landscape changed, API
sprawl emerged as the most serious threat to API
security. The uncontrolled expansion of APIs
within an organization is known as API sprawl,
and it is a typical issue for businesses with
various apps, services, and development
teams. As more APIs are developed, the attack
surface expands and hackers become more
interested in them. The problem is that APIs are
not usually created with security requirements in
mind. As a result, sensitive data such as
personally identifiable information (PII) or
other business data is exposed due to a lack of
authorisation and authentication.
6
API sprawl results in shadow and zombie APIs,
which further jeopardize API security. A zombie
API is a vulnerable, abandoned, out-of-date, or
forgotten API that adds to the API security
danger environment. These APIs were useful at one
point, however, they were eventually superseded
by newer ones. As firms work on developing new
products or services, they overlook the
previously existing APIs, allowing threat actors
to infiltrate the weak API and obtain critical
data. Shadow APIs, on the other hand, are
third-party APIs that are frequently established
without sufficient oversight and hence go
untracked and undocumented. Failure to safeguard
against shadow APIs results in reliability
difficulties, unintended data loss, penalties for
noncompliance, and increased operational costs.
7
Furthermore, the introduction of new technologies
such as the Internet of Things (IoT) has made
maintaining API security more complex. With more
internet-connected devices that can be accessed
remotely, any insufficient security measures
might result in illegal access and significant
data breaches. Furthermore, generative AI systems
can bring security risks. AI algorithms can be
used by hackers to find flaws in APIs and launch
targeted attacks.
8
Best practices to improve API security amid
rising threats
API security has become a key concern for
enterprises, necessitating a comprehensive
cybersecurity strategy to mitigate threats and
vulnerabilities. To increase API security,
developers and security teams must work together
to apply best practices such as those listed
below Discover all the APIs API discovery is
essential for identifying modern API security
risks such as zombie and shadow APIs. Security
teams are trained to secure mission-critical
APIs, but discovering internal, external, and
third-party APIs is equally important for
improving API security.
9
Organizations must invest in automated API
discovery technologies that detect every API
endpoint and offer visibility into which APIs are
operational, where they are located, and how they
work. Developers should additionally monitor API
traffic by incorporating API gateways and
proxies, which can detect the presence of shadow
APIs. Creating regulations that specify how APIs
are documented, utilized, and managed also aids
in the discovery of undiscovered or vulnerable
APIs.
10
Assess all APIs via testing As API security
threats become increasingly ubiquitous, security
teams can no longer rely on traditional testing
methodologies. They must use advanced security
testing methodologies such as SAST (static
application security testing). It is a white-box
security testing method that detects
vulnerabilities and fixes security problems in
source code. Giving developers fast feedback
allows them to write secure code, which leads to
secure applications. However, because this
testing cannot uncover vulnerabilities outside of
the code, security teams should consider
employing alternative security testing methods to
increase security standards, such as DAST, IAST,
or XDR.
11
Adopt a Zero Trust security framework Users must
also authorize and authenticate themselves in
order to access the data, which helps to reduce
the attack surface. To access them and help
decrease the attack surface, users must approve
and authenticate themselves. Furthermore, APIs
can be divided into smaller units with their own
set of authentication, permission, and security
standards by employing Zero Trust architecture
(ZTA). This provides security architects with
greater control over API access and improves API
security.
12
API posture management API posture management is
another excellent method for assisting
organizations in detecting, monitoring, and
mitigating possible security threats caused by
weak APIs. Various posture management
technologies constantly monitor the APIs and
alert them to any suspicious or unauthorized
activity. This allows enterprises to respond
quickly to API security issues while also
reducing the attack surface. These solutions
also do frequent vulnerability scans on APIs to
look for security problems, allowing enterprises
to take steps to improve API security.
Furthermore, these solutions enable API auditing
and verify compliance with key industry
requirements such as HIPAA or GDPR, as well as
other corporate policies to preserve transparency
and maximize overall security standards.
13
Implementing API threat prevention Improving API
security is a continual endeavour thus, dangers
might exist despite tight monitoring and security
rules. This highlights the importance of using
proactive API threat prevention solutions that
identify and mitigate potential API attacks that
have a negative impact on a business. API threat
prevention encompasses the application of
specific security solutions and techniques like
threat modelling, behavioural analysis,
vulnerability scanning, incident response, and
reporting. Organizations can also avert data
breaches and ensure continued company operations
by continuously monitoring, imposing encryption
or authentication measures, or limiting API rate
restrictions.
14
Conclusion
Organizations face significant issues in
safeguarding APIs from malicious actors,
resulting in unauthorized access and potential
data breaches, as API adoption grows. As a
result, every developers primary obligation is
to ensure API security. This can be accomplished
by implementing methods such as identifying all
APIs, completing security testing, implementing a
Zero Trust strategy, utilizing API posture
management tools, and implementing API threat
prevention strategies. By implementing these
principles, security teams can limit the API
danger surface, assure the security of all APIs,
and remain compliant with industry standards.
