An Introduction to Network Security Threats and
Defenses in 2023

What Is Network Security?
Network security is a massive subject that
includes a wide range of processes, policies,
rules, standards, frameworks, software, and
hardware solutions. Its major purpose is to
safeguard a network and its data against various
dangers such as attacks and breaches. Access
controls, application security tools, virus and
antivirus software, network analysis, firewalls,
virtual private network (VPN) encryption,
endpoint protection, online, and wireless
security are all common components of a network
security program.
3
What Are the Top 5 Network Security Threats in
2023?
While predicting the most significant dangers is
difficult, the following threats are regarded as
top priorities by practically every enterprise
and network security professional and are
expected to grow in importance in 2023.
4
Ransomware Ransomware is malicious software
(malware) that encrypts data on a victims
machine and demands money to unlock the ransomed
material and restore access to the victim. The
ransom is typically paid in cryptocurrencies such
as Bitcoin, allowing the cybercriminal to stay
anonymous.
5
Ransomware is becoming increasingly common as a
result of the dark webs availability of
ransomware kits and Ransomware as a Service
(RaaS). These goods and services enable thieves
to acquire and utilize tools to develop
ransomware with specific capabilities at a low
cost. Scareware, encryption malware, master boot
record ransomware, and mobile ransomware are
examples of common ransomware kinds.
6

• API Attacks
• These attacks make use of Application Programming
  Interfaces (APIs) for malicious purposes. APIs
  are targeted by threat actors because they
  promote web-based interactions and can aid in the
  launch of the following attacks
• Injection- This happens when threat actors embed
  harmful malware into vulnerable software. SQL
  injection (SQLi) and Cross-Site Scripting (XSS)
  are two common injection techniques.

7

• Denial of Service (DoS) or Distributed Denial of
  Service (DDoS)- By overloading a targeted system
  with bogus traffic, threat actors can slow it
  down or render it completely unavailable to its
  intended users.
• Data exposure- Passwords, session tokens,
  private health information (PHI), and financial
  data such as credit and debit card information
  are frequently processed and transferred by web
  apps. This data may be exposed due to a lack of
  security safeguards.

8
Social Engineering Attacks These attacks employ
psychological manipulation techniques such as
deceit and coercion to persuade a victim to aid
in the attack. Phishing is a typical social
engineering approach in which an individual is
duped into performing a specific action, such as
opening a malicious attachment, clicking a
malicious link, or disclosing confidential
information, such as login credentials. Phishing
emails, business communications tools, and social
media are commonly used. When the threat actor
sends SMS text messages, the attack is known as
smishing (SMS phishing), and when the danger
actor calls, the attack is known as vishing
(voice phishing). Another prevalent tactic that
targets a specific person or group is spear
phishing.
9
Supply Chain Attacks Supply chain assaults take
advantage of an organizations links with
externally linked parties. It entails leveraging
established trust connections such as third-party
access granted to suppliers and vendors, trusted
external software authorized to release updates,
and third-party code such as open-source
components used by the company.
10
A supply chain strike can cause severe damage to
multiple parties at the same time. If a
trustworthy entity on a supply chain with
authorized access to several organizations is
compromised, it impacts all of these parties. In
the SolarWinds assault of 2020, for example, a
threat artist was able to incorporate malicious
code into a SolarWinds update that was
distributed to all SolarWinds customers, damaging
connected data and crucial infrastructure.
11
Fileless Malware Attacks Fileless malware is a
type of malware that does not require the
installation of a file on the victims computer
to execute. Instead, it uses existing computer
tools and processes to carry out its harmful
activity. Because it does not leave a trace of a
malicious file on the system, it can be more
difficult to identify and remove.
12
Fileless malware can be distributed by phishing
emails or drive-by downloads, in which the
victims machine is infected merely by visiting a
compromised website. Once active, it can execute
code in memory, manipulate registry keys, or
carry out attacks using legitimate tools such as
Windows Management Instrumentation (WMI) or
PowerShell. Because Fileless malware leaves no
files on the system, it can be difficult to
identify using typical security solutions that
check for known malware files.
13
Which Network Security Technologies and Solutions
Will Be Popular in 2023?
The three solutions listed below are gaining
traction and are expected to become common
network tools in 2023 and beyond. 1. Extended
Detection and Response (XDR) Extended Detection
and Response (XDR) is a security strategy that
focuses on real-time cyber threats. It entails
analyzing and monitoring network traffic and
activity for signals of suspicious or malicious
behavior, as well as remediating risks, using
modern technologies such as machine learning and
artificial intelligence.
14
XDR solutions are intended to provide a complete
picture of an organizations security posture and
to assist security teams in identifying and
responding to threats more quickly and
effectively. They often include capabilities like
log management, event analysis, and incident
response, as well as the ability to automate
specific operations and procedures. To provide
an additional layer of protection against cyber
threats, XDR can be used in conjunction with
typical security solutions like firewalls,
antivirus software, and intrusion detection and
prevention systems. It is especially beneficial
to enterprises that must monitor and safeguard
huge, complex networks with a significant volume
of traffic and activity.
15
2. Zero Trust Network Access (ZTNA) Network
traffic is often separated into trusted and
untrusted categories in a classical network
security model, with some segments of the network
considered more secure than others. The zero
trust paradigm, on the other hand, believes that
all traffic is untrusted and must be confirmed
before access to network resources is granted.
This method is intended to protect against both
internal and external network threats.
16
Organizations often employ technologies such as
multi-factor authentication, network
segmentation, and micro-segmentation to regulate
access to network resources and minimize the
spread of threats while implementing a zero-trust
paradigm. The purpose of Zero Trust Network
Access (ZTNA) is to limit a networks attack
surface, making it more difficult for attackers
to exploit.
17

• When considering whether to give access to
  network resources, a ZTNA system takes into
  account a number of contextual considerations.
  These elements may include
• The user or device requesting accesss
  identification.
• The users or devices location.
• The device that is being used.
• The network resources that are being used.
• The users or devices security posture.

18
Secure Access Service Edge (SASE)
SASE is a new security category that offers
managed network protection. It applies security
regulations for remote users and cloud services
while bypassing the organizations data
centers. SASE is a cloud-based service that is
built on a Software-Defined WAN (SD-WAN)
infrastructure. Firewall as a Service (FWaaS),
Cloud Access Security Broker (CASB), Zero Trust
Network Access (ZTNA), and Secure Web Gateway
(SWG) are among the managed security options
available. It can support large businesses and
provide unified policy management and safe access
across hybrid environments as a cloud-based and
distributed product.
19
Conclusion
Network security is an important component of
cybersecurity because it protects networks,
systems, and data from unwanted access, attacks,
and other destructive actions. Organizations must
be aware of a wide range of network security
risks, including ransomware, social engineering,
supply chain attacks, and API attacks.
Organizations can guard against these threats by
implementing a number of network security
solutions and technologies. Organizations can
lower the risk of network security breaches and
protect their sensitive information and assets by
implementing these steps as 2023 begins by taking
activities to protect themselves against some of
these typical threats.
