The number of large organizations being hacked into is at a record high; and the overall cost of security breaches to UK plc is now billions of pounds a year, a new survey of 447 UK businesses shows.
In the last year, one in seven large organizations has detected hackers within their systems – the highest level ever recorded since the survey started in the early 1990s. Furthermore, 70 percent of large organizations have detected significant attempts to break into their networks in the last year, which is another record high.
These are some of the key findings from the 2012 Information Security Breaches Survey (ISBS) by PwC in conjunction with Infosecurity Europe and supported by the department for Business, Innovation and Skills.
On average, each large organization suffered 54 significant attacks by an unauthorised outsider, twice the level in 2010, while 15 percent of large organizations had their networks successfully penetrated by hackers. The average cost of a large organization’s worst security breach of the year is £110,000-£250,000 and £15,000-£30,000 for a small business.
Chris Potter, PwC information security partner, said:
“The UK is under relentless cyber-attack and hacking is a rising risk to businesses. The number of security breaches large organizations are experiencing has rocketed and as a result, the cost to UK plc of security breaches is running into billions every year. Since most businesses now share data with their business partners across the supply chain, these numbers are startling and make uncomfortable reading for business leaders.
“Large organizations are more visible to attackers, which increases the likelihood of an attack on their IT systems. They also have more staff and more staff-related breaches which may explain why small businesses report fewer breaches than larger ones. However, it is also true that small businesses tend to have less mature controls, and so may not detect the more sophisticated attacks.”
Apart from hacking, the survey shows that organizations are experiencing many data protection breaches, data loss events and computer frauds, particularly those that haven’t invested in staff education. The vast majority of respondents had a security breach in the last year: 93 percent of large organizations and 76 percent of small businesses. The most serious breaches result from failings in a combination of people, process and technology, showing the importance of investing in all three aspects.
Outsider attacks have increased, especially against large organizations. There is a marked contrast in the average number of breaches suffered by small and large organizations affected. On average a large organizations now faces one attack per week while for small businesses it is one a month and hacking attacks make up the largest single component.
All sectors reported attackers on the Internet trying to impersonate them; financial services and government bodies were hit most, often reporting ‘phishing’ attacks several times a day. Customer impersonation and identity fraud remain high (up threefold from 2008) with all sectors affected but financial services companies have now overtaken retail. Criminals currently appear to find it easiest to make money by impersonating the customers of banks. One in eleven respondents reported that an outsider had stolen confidential data, with financial services and utilities providers the worst affected.
Despite the prolonged economic slowdown, most organizations have spent more on security this year than in the previous one. On average, organizations spend 8 percent of their IT budget on information security, and those that suffered a very serious breach were found to spend on average 6.5 percent of their IT budget on security. However, there’s some evidence of complacency setting in among large organizations. Some 12 percent of businesses say senior management give a low priority to security, while 20 percent spend less than 1 percent of their IT budget on information security. A root cause is that it is hard to measure the business benefits from spending money on security defences. Only 20 percent of large organizations evaluate return on investment on their security expenditure.
