Getting back to normal – eradication and recovery

Once an incident has been properly and comprehensively investigated, it is time to move into the eradication and recovery phase. There may be a good deal of haste in getting to this stage, as there is a strong desire to return to normal operations. While there may be business drivers at play here, rushing eradication and recovery may reintroduce an unidentified compromised system that has been overlooked. In other scenarios, it could be possible to miss the patching of previously compromised systems, leaving them open to the same exploits that previously compromised them or, worse, placing a still-infected system back on the network. For this reason, both eradication and recovery strategies are addressed here.
