Endpoint Protection

Listening to the local radio this morning I heard the story that the BBC has been forgetful with its laptops and mobile phones. Apparently, as reported by the Guardian and various other sites following a Freedom of Information request, that the BBC over two years has misplaced 146 laptops, 65 mobile phones and 17 blackberry devices. It is unknown if these devices were lost or stolen but the main complaint seems to be the cost to the tune of about £240,000. Although about 10% has been recovered this should not be the primary concern.

The primary worry should be the data on those laptops - If we assume that they contained 250Gbyte disks and that on average each disk would be 50% full then that means over 18Tbytes of data in total not including the mobile phones and blackberrys. I accept that a lot of the data is applications and internet related stuff but the implication is there. There is no indication if the data was encrypted or if any of the data was personal or in anyway potentially damaging to the organisations or employees. Perhaps a further FOI request should be made to further clarify.

If the BBC is capaable of losing this amount of information then consider all the organisations of similar size losing similar amounts of information to understand the scale of loss.

The case for DLP is clear. Keep those comments coming!!

First it was the cuts in private sector firms and now it is the public sector. The easiest and quickest cuts that make a difference to the bottom line are to remove people who are usually the largest cost item. Sadly redundancy is now a major occurrence in a working life. I know of many capable, intelligent and hard working people who have been made redundant two or three times in their lives sometimes more. It is increasingly a tool of organisations to quickly get rid of people. In general, redundancy is never executed against the legal guidelines which results in court cases and compromise agreements.

So what has all this to do with Information Security. The removal of staff from an organisation is currently the biggest threat to an organisations information. Redundancy or whatever method is used can result in animosity, resentment, and malicious intent on the part of the former employee. Of course most organisations are understanding and sensitive to emplyees and most follow the rules. However, sales of DLP software has been rising and the most sited reason for purchase is protection of contact databases, intellectual property and sales information from disgruntled employees.

The threat is real and active and who knows how much critical informaiton has been taken by upset and revengeful emplyees without anyone knowing. Please add any comments to this post on your experiences of cost cutting and data loss.

On the 12th December, it was widely reported that another laptopn was taken from MOD Headquarters in central London. This would not normally cause worry as all laptops are encrypted. However, the encryption key was also taken so exposing the information to the thief. It is not known if there is any exposure whilst investigations proceed. However, news items referred to the laptop as a ’secret data laptop’ which gives an indication. It was only in July thsi year (as reported in this blog) that 658 laptops have been stolen from the MOD in the last four years.

Below is one report on the story but the BBC also have reported it

St Albans City and District Council is the latest organisation to lose four laptops with personal data on over 14,000 voters. Files contained names, addresses, dates of birth, signatures, postal vote forms and statements which is all the information required to obtain a bank account.

Councillors were recently debating the loss and how the laptops could be stolen from the actual offices. Even though the data was protected, the portable devices were not physically secured. This goes against council policy of portable devices being physically as well as logically protected.

It also begs the question as to why personal data was held on portable devices. Such data should only be accessed on central resources and users prevented from copying to local devices.  We shall see what lessons will be learned and then forgotten til the next time.

The council needs to develop an information classification with associated policies on protection. A simple Data Loss Prevention product would have prevented the personal data from being copied in the first place but, had it been copied then the data would have been encrypted. It is noted that one of the laptops was left for months on an unused desk with no one knowing that held all this data. This is why an information audit and classification is required to start to get some control.

This story has been widely reported so use these links for more detail (such as there is)!!

The Information Commisioners Office (ICO) or the privacy watchdog has published figures on data breaches that makes disturbing reading. What’s more is that the ICO  is getting so concerned that it will be introducing fines on comapnies and public bodies that recklessly or deliberately break the rules. Fines up to half a million may be imposed on losses of information. In total, 434 organisations reported data security breaches in the past 12 months, up from 277 the year before. This is what Deputy information commissioner David Smith said: “The majority of organisations get data protection right, but regrettably a significant minority of management teams are failing to take data protection seriously enough. Unacceptable amounts of data are being stolen, lost in transit or mislaid by staff. Far too much personal data is still being unnecessarily downloaded from secure servers on to unencrypted laptops, USB sticks, and other portable media.”

Well what a surprise! But what is really interesting and scary is that there are fines coming! But I thought that if you breached the Data Protection Act then you would be fined or sued anyway. However, what is clear is that this affects all businesses; large or small; SMB or large multinationals. So Data Loss Prevention is for all organisations that have personal data stored but it is not sufficient to just use device control, the ICO is saying any data loss from any channel! So does that mean that first generation products that really only do encryption and device control will be replaced by the second generation products that provide device, IM, and all the goodies? I think this is a call to action for vendors to smarten up their act and work with others to gain functionality rather than buy and try to integrate.

Latest reports on conficker infections include not only Ealing Council (see previous post) but also Oxford Brookes University, Manchester City Council and Whipps Cross University Hospital NHS Trust. Prior to this, the Houses of Parliament and Ministry of Defence were infected.

So AV has been proved to be powerless with this worm and even the DLP vendors do not have any defence as they tend to focus on information passing out of the organisation. Application control should be a part of a DLP solution to stop worms from running and spreading to the rest of the organisation. In most cases it is not as AV and most DLP is focused internally not at the endpoint which is the highest risk. Maybe Windows 7 will save us but how many will implement the application control features and AV and DLP. Not many I fear - Take a look at our sponsors product and if implemented will protect against zero day attacks and Conficker worms as well as the normal DLP features.

Information Week reports We start our Rolling Review of data loss prevention products with Safend Protector Endpoint, the lone entry in our DLP mix whose primary emphasis is endpoint security. The other players have strong DLP capabilities at both the network level and the endpoint, but we wanted to include a company that operates exclusively in the endpoint market because not all IT shops want, or can afford, a soup-to-nuts system from the likes of RSA, Websense, or Symantec (NSDQ: SYMC).

Regardless of how large or complex your organization is, battling data loss threats must start with an emphasis on the endpoint. Safend estimates that 60% of corporate data resides on endpoints, and that’s where Safend Protector Endpoint aims its DLP resources.

Computer Weekly reports F-Secure, Kaspersky and BitDefender have been hacked via SQL injection and cross site scripting techniques.

Kaspersky is thought to have had a breach in its US website databases holding information like customer details. F-Secure was thought to have only leaked virus statistics.

Kaspersky reported that they had fixed the vulnerability within 1 hour of detection.

The BBC reports that a man from New Zealand found that his MP3 player which he bought from a shop in Oklahoma contained sensitive information about military personnel. The data contained names and telephone numbers of soldiers including details of pregnant personnel and even some mission information.

The data is thought to date back to 2005 and isnt thought to compromise national security. There were also similar breaches in Afghanistan in 2006 where shops outside the main US base had stolen flash drives containing sensitive data.

In the current climate of data mobility, some level of encryption and security policy is becoming vital to protecting sensitive data.

Network World reports on the third security related purchase by CA in recent times. Their new acquisition is the data leak prevention vendor Orchestria. Orchestria provide a number of DLP and information compliance products. Symantec also use Orchestria’s smart tagging technology for use in their Enterprise Voltage product.

CA is said to be working on solutions to administer access control and set security policies based on a users role and identity. Adding Orchestria’s technology and experience to the company will strengthen their DLP offering and compliment their existing product range.
