The most expensive types of security breaches are employee fraud, cyber espionage, network intrusion and the failure of third party suppliers. The average budget required to recover from a security breach is $551 000 for enterprises and $38 000 for small and medium businesses.
These are some of the findings from a worldwide survey of more than 5 500 companies in 26 countries, including South Africa, conducted by Kaspersky Lab in co-operation with B2B International in 2015.
A serious breach of IT security systems leads to many business issues. With damage being so diverse, it’s sometimes hard for the victims themselves to estimate the total cost of a breach. The methods used for this survey relied on data from previous years to pinpoint areas where companies have to spend money following a breach, or lose money as a result of a breach. Typically businesses have to spend more on professional services (such as external IT experts, lawyers, consultants, etc.), and earn less due to lost business opportunities and downtime.
The probability of each separate consequence also varies and this, along with the size of a company has to be taken into account. A similar method was used to estimate indirect spend: the budget businesses allocate after the recovery, but is still connected to a security breach. So, on top of the aforementioned figures, businesses typically pay from $8 000 (SMBs) to $69 000 (enterprises) on staffing, training and infrastructure upgrades.
An average breached enterprise bill includes:
* Professional services (IT, risk management, lawyers): up to $84 000 with a probability of 88%
* Lost business opportunities: up to $203 000 and a 29% probability
* Downtime: up to $1,4-million, at a 30% probability
* Total average: $551 000
* Indirect spend: up to $69 000
* Including reputation damage: up to $204 750
Nine out of 10 companies that took part in the survey reported at least one security incident. However, not all incidents are serious and/or lead to the loss of sensitive data. Most frequently a serious security breach is the result of a malware attack, phishing, leaks of data by employees and exploited vulnerable software.
Cost estimation provides a new look at the severity of IT security incidents and the outlook for SMBs and enterprises is slightly different.
Large companies pay significantly more when a security breach is the result of a trusted third party failure. Other expensive types of breaches include fraud by employees, cyber espionage and network intrusion. SMBs tend to lose a significant amount of money on almost all types of breach, paying a similar high price on recovering from acts of espionage as well as DDoS and phishing attacks.
“We have not seen too many reports on the consequences of IT security breaches, estimating a loss in real money. It is hard to come up with a reliable method of producing an average, but we understood that we had to do it, to bridge the theory of the corporate threat landscape with business practice. As a result, we have a list of corporate threats that caused the most significant damage – the ones we believe businesses should pay the utmost attention to,” comments Brian Burke, head of the market intelligence team at Kaspersky Lab.
