Cyber Security today

IT security (or "Cyber Security") problems are becoming more and more complicated. How would you respond to the challenge? Would you apply proactive IT protection with multiplelayers, so that every layer will raise the security level? What kind of challenges will bring mobility, new terminal devices and the increasing use of email and other services through advanced mobile phones?

Viruses and spam are a drastically increasing international problem. The costs caused by them are counted in billions of euro. Spam handling causes direct expenses. Companies whose employees use their effective working time for problem solving every month for several hours are paying for this. Expenses arising from viruses are harder to foretell; in worst cases they result in years of additional work.

In Finland a worm has closed down the offices of Sampo and Nordea Banks; in the USA the targets were automatic cash dispensers. Worms have also stopped trains in the USA and Australia, as well as causing the cancellation of flights all around the world. In Sweden a virus hit hospitals; in Taiwan postal offices. The slammer worm virus managed to get through to an atomic power plant in Ohio, USA.

The border between spam and viruses is blurry. Spam messages are also containing more and more viruses. The latest threat is “phishing” meaning criminal search for information like passwords etc. Those messages look like junk mail but their contents invite the receiver to go to a certain web site and to download a spy application. The Phishing frauds are getting more advanced and becoming the fastest growing field in web crimes. Samples of various spam messages »

Continuous process

IT security and its maintenance is a continuous process. The first viruses arrived by the eighties, and hacking began to increase from the mid-nineties. At these times the creators of viruses and the hackers used to be separate groups. At the end of the nineties, when email traffic became common, the email worms arrived. Email is in fact the most common way to spread viruses.

The virus creators and hackers started to collaborate in the first half of 2000. The outcome was the viruses with complicated variety and combinations. The newest products are malwares, intrusion applications, and spywares, which operate, amongst other things, as information cracking tools. The time window for virus protection applications has diminished during the last few years. The amount of unknown viruses is continuously increasing. They are blocked with various systems based on heuristics. Investment required by information security companies has increased during this time and this growth is expected to continue. Companies either concentrate on security themselves or outsource it to specialists.

Outsourcing brings remarkable cost savings and at the same time the company is able to allocate more time to its own line of activities. The outsourcing of IT security has risen during the last few years to the top of the most outsourced services. Previously, companies took care of it themselves, but due to the fast development of malware, more and more companies are now outsourcing their IT security maintenance to professional service providers for better protection.

Is Outsourcing the answer?

Growth in outsourcing is expanded by companies who want to save costs, and concentrate on their main line of activity. According to research company IDC, companies are outsourcing their information security issues because the field has become more complicated. Companies have to deal with security issues in the turmoil of new operating systems, new viruses, remote connections, firewalls, and information security policies. Portable laptops and new smart phones on the market are creating new challenges to IT security. D-Fence centralized, preventive virus protection solution is a rational way to efficiently protect different terminal devices operating in changing environments.

An even greater threat than viruses is the increasing amount of spam. According to research company Gartner, on average half of the emails which arrive in company inboxes are junk mail. This is also confirmed by our surveillance statistics. The current amount of spam is already exceeding 90 percent of all traffic.

IT security and its maintenance have been demanding more and more attention and additional investments. The easiest way to control this circle is to outsource these matters to a specialist service provider. The information security of tomorrow is created today. This is where outsourcing is the strongest and most cost effective option.

Maximum security with cost savings

In information security protection the same rule applies as in choosing other goods and services: the cheapest solution is rarely the best. On the other hand, one can make endless investments in information security without getting 100 per cent security.
