Open source databases provide great foundations for high availability — without the pitfalls of vendor lock-in that can come with proprietary software. However, open source software doesn’t typically include built-in HA solutions. This blog provides links to such architectures — for MySQL and PostgreSQL software.

So before matching, the IDS/IPS has to reconstruct a TCP bytestream in the face of packet fragmentation, loss, and out-of-order delivery – a process known as reassembly. When used in prevention mode (IPS), this all has to happen inline over incoming traffic to block any traffic with suspicious signatures.
