Computer Security Companies: What Can They Offer Your Business?

Computer security companies are not numerous, especially outside the major cities, but they have a great deal to offer any organisation that takes information security seriously. Different companies have different emphases: one security consulting firm may concentrate on penetration testing and information security audits, while another information security company may tend to focus more on Active Directory security configuration or managed security services. But one thing that all computer security companies have in common is expertise in information security, of which computer security is only one part.

So what exactly can a computer company offer to your business? Depending on your needs and resources, you may prefer either a managed security solution (where security is outsourced to the selected information firm) or a consultancy arrangement (where the computer security firm audits your existing status and makes recommendations, while your in-house team is responsible for all computer security work). Managed security services include functions such as:

· Round-the-clock monitoring of your network, with intrusion detection and incident response services. · Regular security audits and penetration testing. · Firewall configuration and ongoing management.

For smaller businesses that have no dedicated in-house IT team, the managed security solution is the obvious choice. But even for larger organisations with their own computing department, it can still be preferable to outsource this function to computer security firms. This is because computing security, as against the general IT function, can be highly specialised, and not all teams will have the full range of knowledge and experience required. This is where managed security solutions can bring real value to an organisation.

In addition, the field of IT security is constantly evolving, with new threats and new technologies on a regular basis. Specialised security companies are more likely to stay current with developments, and are more likely to have access to the software and procedures needed to deal with new security situations.

A further reason for outsourcing your firm's information security to outside companies is the fact that this solution can often be cheaper than hiring an in-house team, due to economies of scale. A computer company will be able to leverage the same software and consultants for several clients, and will have standardised procedures for use over several projects. Hence the cost of these resources will be spread over several clients, so that each client pays far less than the full cost for specialist software tools and human experts.

Clearly, computer security companies can provide substantial benefits to an organisation over and above their role as consulting firms. Managed solutions are a growing field, and can offer real value to small firms and even to larger firms as well.

Computer Security in London and Edinburgh

Computer security is a growing field: in London, in Edinburgh, and in the rest of the UK. In the world as a whole, information security has evolved from a specialist discipline to a central component of an organisation's security function. Since the advent of the personal computer in the 1980's, computers have escaped from the data processing centre to colonise every office in the country, and in great numbers. Right behind them is the consequent increased need for computer security, due to the exponential growth in the numbers of malicious hackers and opportunistic cyber-criminals in recent years.

As an industry sector in the UK, computer security is relatively new, whether in London, Edinburgh or other cities and towns. Information security has yet to reach its natural level in most areas of the UK, and in principle there is still room for expansion in at least the major financial and industrial centres, such as Edinburgh. In practice, however, further expansion will probably depend on an increase in awareness at board level of the vital importance of information security to all business types today.

In London, this has translated into a plethora of information security consultancies. The UK's capital city is the location of the British headquarters of international banks, financial services companies, and multinational companies of every type. Many of these organisations are subject to stringent regulatory requirements, which include the need to comply with information security standards. This means that computer security in London is a highly active industry sector, with many specialist consultancy firms, as well as regular conferences (such as the annual Infosecurity Europe conference) and university degree courses in information security (such as the highly-regarded MSc in Information Security from Royal Holloway College, University of London).

However, it is a different picture in other areas of the UK. Even in large cities, such as Liverpool or Edinburgh, there are comparatively few computer security consulting firms, and only a few education or training courses in the subject. This is no doubt due to the comparative lack of large companies that are subject to regulatory pressures on information security governance. Without such pressures, organisations can be tempted to relegate computer security to a lower priority: a policy which may be appealing in the short term, but which risks damaging consequences in the longer term.

This unequal relationship between London (and the south-east of England) and the rest of the UK is not seen only in computer security. Although Edinburgh, for example, is a capital in its own right, and the headquarters of several banking and finance companies, it has only a fraction of the wealth and attractive power of London with regard to employee mobility, senior management posts, and international recognition. This situation has built up over many years, over centuries even, and will not change in a matter of a few years only.

Do Nation States Pose a Threat to Computer and Network Security?

The simple answer to the above question is "Yes".

Most people visualize computer hackers as being grubby techno-geeks who consume multiple cans of caffeine-laced energy drinks while working on their computers. That notion may be true. But are these people the largest group of malicious people on the Internet?

Nation states or countries are, also, major players in the tug of war between those who seek to protect computer networks and those who perpetrate breaches, steal valuable information, and damage critical infrastructure.

The Russian Government, for example, is implicated in squashing the dispute that arose between Russia and Georgia in the Province of South Ossetiain 2008. Computer networks were "hacked" into and critical Georgian computing infrastructure was effectively shut down as Russian tanks rolled across the border and asserted Russian authority. Georgian government computer networks and the Internet itself was overwhelmed and disabled until Georgian leaders capitulated.

Reportedly, the Iranian nuclear processing components at Natanz were seriously damaged due to a breach of network security with an attack described in the media as the Stuxnet worm. The level of sophistication of the attack and the extent to which damage was caused suggests that only a nation or group of nations could have produced and supported such an attack against sensitive industrial controls.

The People's Republic of China is documented as having cultivated a network of civilian crackers who engage in 'informatics warfare' on behalf of the People's Liberation Army. For its part, the government of the People's Republic of China supports information warfare battalions that are schooled in how to crack into networks and infrastructure during the day-time and attack the computing infrastructure of other countries for homework. The losses were recently reported as exceeding the money being made in the international drug trade.

Official Chinese government doctrine embraces the concept of unrestricted warfare that includes fighting a war of informatics to obtain strategic and tactical military advantage. The United States, also, demonstrated its overt interest in information warfare by establishing a "Cyber Command".

Nation states do, indeed, pose a threat to computer and network security of the digital infrastructure. Various nation states are known to have engaged in cyber crime and information warfare. The biggest threats that come from other countries focus upon critical national infrastructures, as well as economic and defense-related espionage rather than just traditional malware like viruses and Trojans.

Businesses, organizations and individuals have confidential information related to their products, research and development and infrastructure that must be protected. International cyber thieves routinely target digital assets and want to enlist the computing resources of others to assist in distributed attacks. On the other end of the scale, nation states and their intelligence services target other nations, individuals, legitimate businesses and research facilities that contain sensitive business data, the loss of which can do harm to another country's national security interests.

Your personal information and ability to do business, as well as national security, are at risk. Crackers and cyber criminals are interested in stealing your computing resources that can be used to increase the intensity of attacks against other systems or to use your Internet presence as a "cover". Cyber criminals would steal proprietary information, your identity and confidential customer information.

Nation states, however, seek to attain strategic and tactical advantages in a global struggle of causes ranging from Marxism and the Islamic Caliphate to anarchy, progressive socialism and liaise faire capitalism.

Peaceful and civilized societies have a great deal to fear from attacks against interdependent cyber resources. A well thought out EMP attack can bring a nation's critical national infrastructure to a halt.
