Description:
BYOD Security Scanning - the ability to assess smartphones, tablets and laptops for vulnerabilities, secure configurations and unprotected data at rest are vital for visualizing the entire security and compliance posture of an organization. BYOD environments are equally important as traditional servers and computers. This paper illustrates that all endpoints can now be scanned for threats regardless of where the device is physically located, anytime and anywhere.)

!!The!demands!of!security,!risk!and!compliance!management!require!BYOD!security!scanning!to!do!more!than!look!for!common!vulnerabilities.!As!stated!earlier,!scanning!for!secure!configurations!and!identifying!confidential!data!such!as!primary!account!number!(PAN)!credit!card!data!or!personal!health!information!(PHI)!are!also!mandatory!for!BYOD!security!scanning.!!The!world!of!mobile!connectivity!introduces!new!challenges!for!identifying!risks,!threats,!and!achieving!compliance.!This!mobile!world!also!requires!that!scanning!technologies!adapt!to!today’s!networks.!It!is!not!practical!or!technologically!sound!to!deploy!appliances!and!complex!software!in!an!attempt!to!secure!BYOD!devices!and!other!endpoints!that!are!mobile!and!not!static.!!!

• Endpoint!Management!solutions!• Remote!Monitoring!and!Management!• Single!SignVon!• Web!Application!Portals!• Email!and!Calendaring!Applications!

2.
