Using Grok filter

[Groove]

Hello, I am pretty new to ELK stack. Currently I am trying to parse my application log using grok pattern. But since my logs are not structured I may have to use grok conditions, because in output I have windows event and deepsecurity logs.

I am trying the below, but It doesn't work:

filter {

 if [message] =~ "\bDeep Security\b" {
    mutate {
      gsub => ["message", "\t", "|"]
      add_tag => [ "Deep Security" ]
    }
    grok {
      match => { "message" => "%{SYSLOG5424PRI}%{SYSLOGTIMESTAMP:devTime}" }
    }
    date {
       match => [ "devTime", "MMM dd HH:mm:ss", "MMM  dd HH:mm:ss" ]
    }
    kv {
      source => "message"
      value_split => "="
      field_split => "|"
    }

Desired result : deepsecurity logs be the same format as windows event logs
