Overview of IT Security in Operations: Fortifying the Digital Core

In the digital arena we are in a state of war which sees an ever growing range of attacks. Cyber criminals, state sponsored teams and internal foes are constantly at us with advanced tools to bring down our systems, steal info, or extort money. In this setting a reactive security strategy is a sure fire way to fail. What we see instead is that companies must take a pro active, wide scale, and constant adaptive approach to security which is a part of the way they do business.

Defining IT Security in Operations

At the base of it, what we see in IT security in operations are the processes, technologies and practices which are put in place by an organization to protect its live IT infrastructure, applications and data from unauthorized access, use, disclosure, disruption, modification, or destruction. Also unlike theoretical security planning which is a0 abstract concept, operational security is in the now  real time defense, incident detection, quick response, and constant improvement as threats present themselves.

It includes the full range of IT asset life which from the start of deployment and configuration to day to day operation, maintenance, and eventually disposal. The base tenets which guide this field are the pillars of information security:.

• Confidentiality: Ensuring that only authorized individuals have access. This also includes protection of sensitive data from unauthorized view or release.
•  Integrity: Maintaining the integrity of data. This includes prevention of unauthorized change or damage to info which in turn guarantees its reliability.
• Availability: Ensuring authorized users’ access to information and systems at all times. We protect against DoS attacks, system failures, and other disruptions which may interfere with access.

A strong operational security framework that which applies these principles in a continuous fashion for the betterment of business continuity and also in the growth of trust with customers, partners and stakeholders.

The Dynamic and Dangerous Threat Landscape

The issue of IT security in operations is at a premium due to the growing rate and complexity of cyber threats. What is a large issue today may be put in the shade by an even more advanced threat tomorrow. To that we see key threats which operational security teams are dealing with include:.

• Malware and Ransomware: Malicious software that which to disrupt and damage or which to gain unauthorized access to computer systems. Ransomware in particular encrypts data and holds it for ransom often bringing down organizations.
• Phishing and Social Engineering: Deceitful methods used to get individuals to share private info or to do actions which in turn damage security. Also we see that which human element is played upon and it still is the main vulnerability.
• Insider Threats: Present or past employees, contractors, and business partners that have valid access to systems.
• Denial-of-Service (DoS/DDoS) Attacks: DDoS attacks which disable access to an online service.
• Zero-Day Exploits: In which there are flaws in software or hardware of which the vendor and the public are not aware, these are very dangerous until a patch is developed and deployed.
• Supply Chain Attacks: Targeting weak points in a company’s supply chain to get to the primary target.
• Advanced Persistent Threats (APTs): Highly complex and long term attacks which are carried out by very resourceful groups (which in many cases are supported by the state).
  The security breach’s economic impact is great which includes recovery costs, regulatory fines, legal fees, and also reputational damage that results in great loss of business and customer trust. Thus a multi layer approach which is pro active is not a luxury but a basic requirement.

Core Components of IT Security in Operations

Effective full spectrum information security in the IT domain requires a combined approach which puts together many different controls, processes and technologies. These elements may form the foundation of a detailed IT Information Security Operation Playbook which in turn guides the organization’s security actions and responses.

1. Security Governance and Policy: This base layer which sets the framework for information security across the organization. We put in place security policies, standards and guidelines, we also see to it that we are compliant with relevant laws (eg. GDPR, HIPAA, CCPA) and industry regulations and we instill a security aware culture from senior management down.
2.  Risk Management: A constant process of identifying, assessing, prioritizing, and mitigating IT security risks. We determine what the threats and vulnerabilities are, we evaluate the probability and impact of each, and we put in place controls which bring risk to a bearable level.
3.  Access Control and Identity Management: Ensuring that access to our resources is granted only to identified and approved entities. We do this by putting in place strong auth methods (for instance Multi Factor Auth  MFA) which require more than one form of identification for access, we also apply the principle of least privilege which means we give users only what they need for their jobs and we put in place robust identity and access management solutions.
4. Network Security: Securing our network infrastructure against unauthorized access, use and disruption. We do this by means of firewalls, intrusion detection and prevention systems (IDS/IPS), virtual private networks (VPNs), network segmentation, and secure network device configuration.
5. Endpoint Security: Securing of workstations, laptops, mobile phones and servers which connect to the network. We put in place anti virus software, Endpoint Detection and Response (EDR) solutions, device encryption, and host based firewalls.
6. Data Security: Through out the life of data  at rest, in transit, and in use. We include data encryption, data loss prevention (DLP) solutions, data classification, secure data storage practices, and regular data backups.
7. Security Monitoring and Logging: Continuous monitoring of IT systems and networks for signs of unusual activity. This includes the collection and analysis of security logs, use of Security Information and Event Management (SIEM) tools, and creation of Security Operations Centers (SOCs) for which we have real time threat analysis.
8. Vulnerability Management and Patching: Regularly we identify, assess, and remediate security vulnerabilities in systems and applications. We do this via regular vulnerability scans, pen tests, and a methodical approach to the application of security patches and updates as they come out.
9.  Incident Response and Disaster Recovery: Developing out in depth plans and procedures that address security incidents (of which breaches, malware outbreaks are examples) as well also to issue of business continuity should major outages occur. The IT Information Security Process Playbook is key here, also includes step by step guides for different incident scenarios.
10. Security Awareness Training: Training employees on security best practices and to recognize common threats (like phishing) and their role in the security of the organization. As the human element is the weak point at times, through proper training we may turn that around to become the strongest element of defense.
11. Vendor and Third-Party Risk Management: Assessment and management of security risks which third party vendors and service providers present to our data and systems. Also this is of great importance as we see an increase in supply chain attacks.

Implementing an Effective Security Posture

Implementing and which is the continuous effort of putting in place and0which is the maintenance of strong IT security in operations we have see that it requires a commitment from all levels. We have also seen the value of a well thought out IT Information Security Process Playbook which is a key resource  it details out standard procedures for everything from the routine security checks to the in depth incident remediation. This Playbook in turn guarantees consistency, efficiency and effectiveness in security operations which in turn allows teams to respond in the same -- proven -- way to a wide range of issues.

Also we see that which is important for a company to do is to integrate security in the development process (DevSecOps), adopt automation for routine tasks, and at the same time create a culture of continuous improvement which we put in practice through regular audits, security assessments, and learning from past incidents. Also it is of great import that leadership buy in this initiative and we put in the resources required to see security as an investment and not a cost.

Challenges and Future Trends

Despite progress, organizations still struggle with issues in operational security which includes a persistent talent gap in cyber security, managing the complex world of hybrid cloud and IoT devices and securing legacy systems. As we look to the future the environment will continue to change with incepted trends:.

• Artificial Intelligence and Machine Learning (AI/ML): In the former they are used as tools for security defense (e.g. anomaly detection, threat prediction) and in the latter they are used by attackers as advanced weapons.
• Zero-Trust Architectures: A security model which puts forth the idea that no one is to be trusted, we instead must verify all access to resources which includes that of users and devices at all times and in all places within or out of the network.
• Increased Regulatory Scrutiny: Governments all over the world are passing in more strict data protection and cyber security regulations which in turn is putting greater accountability on organizations.
• Quantum Computing: A far term issue which is put forth to break present encryption which in turn will require study of quantum safe cryptography.

Conclusion

The report on IT Security in Operations presents a picture of a very complex, dynamic, and at the same time very critical field which is fundamental to the success and growth of any modern business. It is a constant struggle against an ever evolving adversary which requires vigilance, adaptability and unshakeable dedication. By adopting a wide scale, pro active approach which includes strong policies, well defined processes (as outlined in an IT Information Security Process Playbook), advanced technologies, and a security conscious culture organizations may greatly improve their resilience, protect their digital assets and secure their future in a very connected and dangerous world.
