Protecting FOSS systems

rsing WmAO security instead of Wbm is recommended. BesidesI the shared key of WmA security should be long and complex enough to stop directory brute-force attacks. cor large corporationsI the iayer-T wireless security software should be installed on client nodes as well as AmsI to further strengthen the encryption process. cor clpp systemsI XsLng an ;.509 FHUWLfiFaWH Rn HLWKHU Hnd RI WKH wLUHOHss communication can help achieve cheaper yet effective sHFXULWy. 0RsW IaPRXs flaYRXUs, sXFK as DHELan and 8EXnWX, support WmAO security with trimmings such as AbpI qhfm and /(AP.

While there is no single solution to protect wireless networksI an appropriate combination of the techniques mentioned above can achieve adequate security. Wireless monitoring audits are an important activity that needs to be done by network administrators at regular intervals.
