The Culture Has Changed, and So Must Our Approach

Perspectives about security have changed It’s a roadblock It enables the business

It’s not my problem Everyone needs to own security

Technology metamorphoses Disjointed point solutions Integrated architectural play

Physical infrastructure – slow to change Virtual infrastructure – flexible, dynamic, change-ready

The office contains all my stuff My mobile devices are my office (Data, Apps, Voice, Video)

Architecture approach has changed Perimeters as the control point Identity is the new perimeter

Focus on protecting the infrastructure Focus on protecting the data

Capabilities not tightly aligned Services, Service Categories, Service Offerings

The threats have changed Individuals Organized criminals/hacktivists

Disparate groups Nation State

Capture individual users data Gain access to your Data (and your customer ‘s data)

Cisco Confidential 12© 2013-2014 Cisco and/or its affiliates. All rights reserved.

What are the threats for the endpoints?

• Phishing and Data Exfiltration

• Network attacks

• Malware/Exploits (RansomWare: Cryptolocker)

• Advanced Persistent Threats (APTs) - Foreign threats that are highly targeted and financially motivated to retrieve intellectual property.

• Lost/Stolen Device

How are they addressed

• Data Protection: Encryption (Lost/Stolen desktops)

• Known Threats: VirusScan (file scanning)

• Unknown Threats/Exploits: HIPS (IPS/behaviour scanning + Firewall)

• Global Threat Intelligence: Cloud-based protection
