Collaborations between such entities present an effective approach to handle the dynamic nature of cyber threats. Therefore, understanding their role and impact on our everyday digital lives is imperative for every user in this interconnected era.

Cyber security, also referred to as information technology security, is the practice of protecting networks, programs, computers, and data from digital attacks, damages, or unauthorized access. What exactly does a person do in cyber security? This question highlights the complex and broad-ranging nature of this field. But, to break it down simply, professionals in cyber security safeguard the digital world from threats.

These threats can take a variety of forms, including malware, ransomware, phishing, or distributed denial of service attacks. Each of these threats aims to either destroy, expose, alter, or disable critical information, often with harmful results. Cyber security professionals play a critical role in preventing and mitigating these threats.

At the core of their role, cyber security professionals focus on the three foundational elements of cyber security: confidentiality, integrity, and availability (also known as the CIA triad). Confidentiality refers to protecting information from unauthorised access, integrity ensures that the information is correct and unaltered, and availability makes sure that information and systems are accessible to those who need them.

On a day-to-day basis, a cyber security professional’s tasks may include installing and maintaining firewalls, creating security plans, pen-testing (which is a simulated cyber attack to find vulnerabilities), investigating breaches, and regularly updating and patching systems. They play an important role in not only preventing attacks but also in responding swiftly and effectively when an attack occurs.

In the larger context, a lot of their work is about risk management. This can involve assessing a company’s security posture, identifying vulnerabilities, and proposing improvements. It’s a continuous process of safeguarding and fortifying digital assets against ever-evolving threats.

Another significant part of the work in cyber security involves the cyber security business. Like other corporate sectors, cyber security is a business that requires management, strategy, and operations. Understanding the business side of things is crucial as it allows professionals to align security measures with the organisation’s objectives.

The cyber security business involves a host of activities, such as managing budgets, making cost-benefit analyses for security investments, dealing with legal, regulatory, and compliance issues, and interacting with stakeholders to discuss security issues. It also includes staying updated with the newest trends and best practices in the industry.

Additionally, in the cyber security business, experts often play a role in creating policies and procedures that dictate how the organisation responds to cyber threats. These protocols cover things like disaster recovery plans, user access controls, and incident response protocols.

Overall, working in cyber security is a complex task which involves both technical acumen and strategic thinking. It’s a demanding, rapidly-evolving field, but one that offers a lot of opportunities for those who are up for the challenge. If you’re interested in problem-solving, technology, and securing the digital world against threats, then a career in cyber security could be a perfect fit for you.

Given the increasing reliance on digital networks and systems, the demand for professionals in the field of cyber security is expected to rise in future years. As cyber threats become more sophisticated, the need for skilled personnel to combat these threats will continue to grow, making cyber security a promising arena for career growth.

Technological measures protecting works distributed on Compact Discs have been found to pose unreasonable security risks to consumers personal computers, corporate and government networks and the information infrastructure as a whole. Vulnerabilities inherent in widely distributed CD protection measures create the potential for a frightening range of abuses.

Viruses and Trojan horses are already leveraging these technologies to hide from antivirus programs and system administrators. Exacerbating the unacceptable risks posed by these technological protection measures, is that fact that the uninstallers provided to remove these measures pose additional security risks allowing a malicious web site to hijack a consumer s computer.

You have to be aware of several vulnerabilities regarding the XCP Digital Rights Management (DRM) software by First 4 Internet, which is distributed by some Sony BMG audio CDs. The XCP copy protection software uses “rootkit” technology to hide certain files from the user. This technique can pose a security threat, as malware can take advantage of the ability to hide files. We are aware of malware that is currently using this technique to hide.

One of the uninstallation options provided by Sony also introduces vulnerabilities to a system. Upon submitting a request to uninstall the DRM software, the user will receive via email a link to a Sony BMG web page.

This page will attempt to install an ActiveX control when it is displayed in Internet Explorer. This ActiveX control is marked “Safe for scripting,” which means that any web page can utilize the control and its methods. Some of the methods provided by this control are dangerous, as they may allow an attacker to download and execute arbitrary code.

First 4 Internet XCP “Software Updater Control” ActiveX control isincorrectly marked “safe for scripting”

We recommend the following ways to help prevent the installation of this type of rootkit:

Do not run your system with administrative privileges. Without administrative privileges, the XCP DRM software will not install.

Use caution when installing software. Do not install software from sources that you do not expect to contain software, such as an audio CD.

Definition Of A Survivable Computer System

A computer system, which may be made up of multiple individual systems and components, designed to provide mission critical services must be able to perform in a consistent and timely manner under various operating conditions. It must be able to meet its goals and objectives whether it is in a state of normal operation or under some sort of stress or in a hostile environment. A discussion on survivable computer systems can be a very complex and far reaching one. However, in this article we will touch on just a few of the basics.

Computer Security And Survivable Computer Systems

Survivable computer systems and computer security are in many ways related but at a low-level very much different. For instance, the hardening of a particular system to be resistant against intelligent attacks may be a component of a survivable computer system. It does not address the ability of a computer system to fulfill its purpose when it is impacted by an event such as a deliberate attack, natural disaster or accident, or general failure. A survivable computer system must be able to adapt, perform its primary critical functions even if in a hostile environment, even if various components of the computer system are incapacitated. In some cases, even if the entire “primary” system has been destroyed.

As an example; a system designed to provide real-time critical information regarding analysis of specialized medications ceases to function for a few hours because of wide spread loss of communication. However, it maintains the validity of the data when communication is restored and systems come back online. This computer system could be considered to have survived under conditions outside of its control.

On the other hand, the same system fails to provide continuous access to information under normal circumstances or operating environment, because of a localized failure, may not be judged to have fulfilled its purpose or met its objective.

Fault Tolerant And Highly Availability Computer Systems

Many computer systems are designed with fault tolerant components so they continue to operate when key portions of the system fail. For instance; multiple power supplies, redundant disk drives or arrays, even multiple processors and system boards that can continue to function even if its peer component is destroyed or fails. The probability of all components designed to be redundant failing at one time may be quite low. However, a malicious entity that knows how the redundant components are configured may be able to engineer critical failures across the board rendering the fault tolerant components ineffective.

High availability also plays a role in a survivable computer system. However this design component may not maintain computer system survivability during certain events such as various forms of malicious attack . An example of this might be a critical web service that has been duplicated, say across multiple machines, to allow continuous functionality if one or more the individual web servers was to fail. The problem is that many implementations of high availability use the same components and methodology on all of the individual systems. If an intelligent attack or malicious event takes place and is directed at a specific set of vulnerabilities on one of the individual systems, it is reasonable to assume the remaining computer systems that participate in the highly available implementation are also susceptible to the same or similar vulnerabilities. A certain degree of variance must be achieved in how all systems participate in the highly available implementation.

What’s The Difference Between An Attack, Failure, And Accident? How Do These Differences Impact A Survivable Computer System

In many cases when I am discussing the security of systems with customers, the question of business continuity and disaster recovery come up. Most companies that provide a service that they deem critical just know the system needs to be operational in a consistent manner. However, there is typically little discussion about the various events or scenarios surrounding this and that can lead to great disappointment in the future when what the customer thought was a “survivable computer system” does not meet their expectations. Some of the items I like to bring up during these conversations is what their computer systems goal and objective is, what specifically does continuous operation mean to them, and specifically what constitutes an attack, failure, or accident that can cause loss of operation or failure to meet objectives.

A failure may be defined as a localized event that impacts the operation of a system and its ability to deliver services or meet its objectives. An example might be the failure of one or more critical or non-critical functions that effect the performance or overall operation of the system. Say, the failure of a module of code that causes a cascading event that prevents redundant modules from performing properly. Or, a localize hardware failure that incapacitates the computer system.

An accident is typically an event that is outside the control of the system and administrators of a local / private system. An example of this would be natural disasters such as hurricanes, if you live in south Florida like I do, or floods, or wide spread loss of power because the utility provider cut the wrong power lines during an upgrade to the grid. About two years ago, a client of mine who provides web based document management services could not deliver revenue generating services to their customers because a telecommunications engineer cut through a major phone trunk six blocks away from their office. They lost phone and data services for nearly a week.

An now we come to “attack”. We all know accidents will happen, we know that everything fails at one time or another, and typically we can speculate on how these things will happen. An attack, executed by an intelligent, experienced individual or group can be very hard to predict. There are many well known and documented forms of attacks. The problem is intelligence and human imagination continuously advance the form of malicious attacks and can seriously threaten even the most advanced designed survivable computer systems. An accident or failure does not have the ability to think out of the box or realize that a highly available design is flawed because all participants use the same design. The probability that an attack might occur, and succeed may be quite low, but the impact may be devastating.

Conclusion

One of the reasons I wrote this article was to illustrate that it’s not all about prevention. Although prevention is a big part of survivable computer system design, a critical computer system must be able to meet its objectives even when operating under hostile or stressful circumstances. Or if the steps taking for prevention ultimately prove inadequate. It may be impossible to think of all the various events that can impact a critical computer system but it is possible to reasonably define the possibilities.

The subject of survivable computer systems is actually one of complexity and ever evolving technology. This article has only touched on a few of the basic aspects of computer system survivability. I intend on continuing this article to delve deeper into the subject of survivable computer systems.
