Decompressing log files in push mode for Qradar

  • 1.  Decompressing log files in push mode for Qradar

    Posted 24 days ago
    Hello,

    Does anyone use Qradar SIEM in push mode (not the pull mode with the Python script) from the Cloud WAF?

    Our issue is that the logs are compressed by the Cloud WAF with "ZLIB", while Qradar is not able to decompress ZLIB. 

    Imperva's documentation suggest to decompress with the following script -

    csplit -sz 123_345.log -f 123_345.log. /\|\=\=\|/ 
    sed -i '/|==|/d' 123_345.log.01 
    cat 123_345.log.00 > 123_345.log.decompressed 
    zlib-flate -uncompress < 123_345.log.01 >> 123_345.log.decompressed 
    rm 123_345.log.0*
    However we were wondering if anyone has a more native way to do this decompression by the QRADAR itself
    (Not having to go through an additional script/server).

    Thanks,
    Roee

    Hi Rose,

     

    Compression can be disabled from the PUSH connector from the Imperva side so you don't have to uncompress it using that code.

    Thanks Abhishek ,
    We've tried that but the amount of data was so large, it had to be compressed.
