Strengthening infrastructure security (Part I)

Strengthening infrastructure security (Part I)In today’s digital age, infrastructure security has become a paramount concern for organizations worldwide. The rapid proliferation of cyber-attacks in recent years underscores the critical importance of safeguarding critical infrastructure from potential threats. This article delves into the intricacies of infrastructure security, focusing on network and cloud infrastructure as two of the most discussed topics. We will outline key principles, and critical steps in building infrastructure protection, and elucidate the benefits of enhancing infrastructure security software.

The objectives of infrastructure security

Security is a top priority for any organization, particularly those dealing with sensitive data. The surge in cybercrime has exacerbated in recent times and this highlights the urgency of fortifying infrastructure security. In 2021 alone, cybercrime incidents surged by a staggering 600%, with malicious software, ransomware attacks, and crypto-jacking emerging as the most significant vulnerabilities in infrastructure.

The primary goal of infrastructure security is to mitigate risks faced by organizations. Many companies rely on advanced software solutions, encompassing both on-premises and cloud-based systems. Therefore, this article concentrates on network infrastructure security and cloud infrastructure, emphasizing their vulnerabilities.

Levels of infrastructure security

Infrastructure security comprises several levels, each integral to the core of an organization’s operations:

  1. Physical Level: This involves safeguarding the physical locations where software and hardware reside. Security measures encompass lockers, backup generators, security cameras, and more.
  2. Network Level: Network infrastructure security focuses on protecting data during transit. This involves measures like traffic encryption, authentication, and authorization systems.
  3. Application Level: Protecting data within applications is crucial. Security measures here include defense against SQL injections and creating protection systems against malicious software.
  4. Data Level: Protecting data stored in various locations is paramount.

Effective infrastructure security requires managing all these levels comprehensively, as they form the backbone of an organization’s business operations.

Network infrastructure security

Securing network infrastructure is a complex process involving measures to prevent unauthorized access or software modification. This is particularly challenging since network security typically consumes a significant portion of enterprise resources. Network infrastructure comprises numerous hardware and software components, with software components, such as server operating systems, firewalls, and network communication systems, being the most vulnerable.

Key measures for network infrastructure security include:

  1. Access Control: Ensuring that unauthorized users or devices cannot gain access to the network.
  2. Application Security: Implementing measures to block potential threats at the application level.
  3. Virtual Private Network (VPN): Establishing secure channels for network users to prevent data interception.
  4. Behavioral Analysis: Detecting unusual network activity that may indicate a cyberattack.
  5. Firewalls: Configuring firewalls to permit or block specific web traffic.
  6. Wireless Security: Implementing additional protection measures for wireless networks, which are often less secure than hardwired networks.

Cloud infrastructure security

Securing cloud infrastructure is vital, given the increasing prevalence of cloud-based solutions. However, cloud infrastructure poses unique challenges due to its exposure to public networks. Organizations must understand their responsibilities and the security provided by cloud service providers. Three primary models for implementing cloud infrastructure security include:

  1. Public Cloud Security: Public cloud providers ensure infrastructure security but require organizations to secure their data and access.
  2. Private Cloud Security: In this model, organizations have full control over security levels, including native monitoring tools to detect unusual behavior within their workloads.
  3. Hybrid Cloud Security: This model integrates on-premises, public, and private cloud networks. It necessitates a unified security strategy and the secure integration of domains.

As cyber threats continue to escalate, investing in infrastructure security is imperative for organizations. Enhancing security safeguards data and operations yields hidden benefits, such as cost savings through resource sharing and cheaper licenses. Infrastructure security is the foundation upon which a robust security strategy is built, and its importance cannot be overstated. Embracing the principles and practices outlined in this article can significantly bolster an organization’s defenses and reduce the risk of cyber attacks.
