Sir Robert Fry, head of EDS Defence, has said that a portable hard drive which went missing had not needed to be encrypted under Ministry of Defence procedures because it was held in secure premises.
Some in the IT industry may be surprised that portable MoD data does not require encryption if it is held in secure premises.
Fry said he was unable to rule out the malicious use of any data on the missing drive. But he said that "if it was intended for any malicious purpose, we would have had some indication that that was the case before now".
He was being questioned on BBC Radio 5's "Drive" programme, which included an interview with Computer Weekly. The presenter Anita Anand asked Fry: how secure was the hard drive?
He replied:
"The hard drive was not encrypted but neither did it need to be, in terms of the protocols to which we and the Ministry of Defence work, when it sits inside a secure site."
The loss of the drive was discovered last Wednesday and reported by EDS on the same day. But it's not known when the drive disappeared. The Ministry of Defence said in a statement that the hard drive may yet turn up at another secure site. It conceded that the personal information of members of the armed forces might have been "compromised" by the loss of data on the drive.
The 1TB portable hard drive went missing from a secure EDS site at Hook in Surrey.
MPs have criticised the loss of the hard drive, saying that a culture change is needed to prevent personal data going missing.
