5 REASONS WHY
PENETRATION TESTING IS IMPERATIVE FOR YOUR ORGANIZATION
Cybersecurity is of utmost importance, especially in
today’s world. Our world is connected through a fragile network that deals with
internet banking and government infrastructure as DoS attacks, website
defacement, and other cyber-attacks are on the rise.
Global cybercrime costs saw an increase of approximately 27.4%
in the last year alone. Of late, 85% of the companies in the UK and the U.S.
have fallen victim to phishing attacks (9 out of 10 phishing emails carried
malicious ransomware). The number of newly evolved ransomware attacks in 2017
is over 4 times more than in 2016. An organization is hit with a ransomware
attack every 40 seconds; at least 71% of these attacks are successful. The time
taken, on an average, for a company to resolve even one of these attacks is 23
days.
Penetration Testing (or Pen Testing) is a method of evaluating
the security of an information system by simulating an attack from a malicious
source. In simple terms, it is an authorized test to establish how weak your
organization’s cybersecurity is and what you can do to strengthen it. Sadly,
not many companies are comfortable with the idea of reassessing their security
budgets.
It is time for organizations to re-think the security of their
cyberspace with the help of penetration testers. Here are a few reasons why you
should hire a penetration tester:
1.
Security Tools vs. Penetration Testers
Every company has their own set of cybersecurity tools––like
encryption codes, anti-virus software, and vulnerability scanning––but how sure
are you that these tools will be able to protect you in a live attack?
Penetration testers are trained to think beyond the normal and
navigate their way through even the toughest of barriers using a base of
open-source methodologies like Open Web Application Security Project (OWASP),
PTES, NIST800-115, PCI DSS, Information Systems Security Assessment Framework
(ISSAF), Open Source Security Testing Methodology Manual (OSSTMM), etc. as
basic road-map.
They go one step beyond a vulnerability assessment by providing
defense in depth; this also includes exploiting the vulnerabilities identified
during Perimeter Testing, Database Penetration Testing, Log-Management
Penetration Testing, Cloud Penetration Assessment, Network Security Assessment,
Wireless/ RAS Assessment, Telephony Security Assessment, File Integrity Checking,
and other assessments.
2. A
Fresh and Advanced Opinion
Often, a person falls into a set pattern of performing tasks
when completed on a day-to-day basis. This is also the case with ethical
hackers employed in a company. While following a schedule is generally a great
advantage for an organization, it is not the case with penetration testing.
A penetration tester is trained to identify the threats through
a new approach, as well as determine the probability of an attack on
information assets, ensuring a better Return on Investment (RoI) for IT
Security. They provide assurance that the company is operating with an
acceptable limit of information security risks, and are to do so in compliance
with the regulations and industry standards.
3.
Attacks a Single Target as a Whole
You have just learned the various tools and techniques of
ethical hacking, but is that enough to carry you through a full-scale
penetration test?
It is in a moment like this that the penetration tester’s skills
and hands-on experience to stimulate a real-life cyber-attack is important. By
using various methodologies to perform advanced attacks they can identify
Structured Query Language (SQL) injections, Cross-Site Scripting (XSS), LFI,
and RFI vulnerabilities in the organization’s web applications and
infrastructure.
It is through hands-on experience and hours of implementing
knowledge and skill into practice that a penetration tester is able to expose
several vulnerabilities for a single target by aiming a combination of
methodologies at the organization’s cybersecurity.
Very often, a single attack will not show the penetration tester
any vulnerabilities in the organization’s cybersecurity. However, when a single
target is obtained and attacked by various simultaneous attacks, it could lead
to a breach in an organization’s cybersecurity; thus, exposing a vulnerability.
4.
Penetration-Testing Report Writing
Every penetration tester is trained to provide in-detail,
industry-level approved documentation of their findings. This report generally
includes a detailed usage of methodologies: an attack narrative, evidence and
corroboration of any successful penetration findings, and documentation of any
security flaws. Apart from the findings, the report also includes remediation
details to prevent any possible future malicious attacks on the organization.
The penetration tester will also be able to advise you on what
risks must be addressed first based on the amount of risk exposure it involves.
This report will enable the organization to make decisions on
implementing security controls in the organization and patch any flaws. This
also enables the organization and the penetration testers to keep track of the
exploits performed and the information accumulated.
5.
White-Box vs. Black-Box Testing
White-box testing is the method in which the penetration tester
has an authorized view of the internal structure of the organization; black-box
testing provides the penetration tester with little-to-no information about the
organization’s infrastructure.
While white-box testing is certainly a cheaper option, it may
not be the best option for your company––where security is concerned––as it is
highly possible that many threats can go unnoticed.
Black-box testing gives the company the perfect “real-life” perspective
from an unauthorized hacker’s point of view. This enables the penetration
tester to conduct an unbiased test, as they will be working independently. It
also tests the environment the program is running in and is perfect for large
applications. Test cases can also be designed immediately, as the tester does
not have to wait for the development to be completed. The penetration testers
who follow black-box methodology use various application scanners––such as
Boundary Value Analysis (BVA), equivalence partitioning, error guessing, domain
analysis, and many more techniques––to find and exploit vulnerabilities.
Only 38% of global organizations claim they are prepared to
handle a sophisticated cyber-attack––while the estimated average cost of a data
breach in 2020 is said to exceed $150 million. This makes penetration testing a
boardroom agenda. Apart from the aforementioned reasons, a trained penetration
tester is considered one of the finest solutions to discovering vulnerabilities
in your organization, as they also help train the organization’s developers to
make fewer mistakes.
However, keep in mind that while penetration testing can expose
a weak link––giving you an idea of where to tighten security––tests must be
conducted on a regular basis to ensure that the company remains secure at all
times.
