2. Why Center for Internet Security (CIS) Critical Security Controls
Work?
Based on actual
attacks and
effective defenses
Based on priorities
Not one-size-fits-all
solutions

3. 1. Inventory of Hardware
 Authorized and
Unauthorized Devices
– Attackers are
continuously scanning
the target organizations
– Attackers are waiting
for new and
unprotected systems to
be attached to network

4. 2. Inventory of Software
 Authorized and
Unauthorized
Software
–Attackers are
continuously looking
for vulnerable
versions of software
that can be remotely
exploited

5. 3. Secure Configurations of Hardware and Software
 Default configurations
are for ease-of-use
not security
 Open services, ports,
default account or
passwords
–Can be exploitable

6. 4. Continuous Vulnerability Assessment and Remediation
 Scan for vulnerabilities and
address discovered flaws
 Understand and manage
vulnerabilities is a continuous
discovered activity
 Attackers have the same
information
– Race to deploy an attack

7. 5. Controlled Use of Administrative Privileges
 Track and control the
use of administrative
privileges
 Attackers can take
advantage of
uncontrolled
administrative privileges
–Can crack the
password

8. 6. Maintenance, Monitoring and Analysis of Audit Logs
 Collect, analyze audit logs
of events
– Detect an attack
– Recover from an attack
 Sometimes, logs are the
only evidence of an attack
 Attackers can also hide
their activities

9. 7. Email and Web Browser Protections
 Minimize the attack surface
through web browsers
–Fully up to date and patched
–Default – not installing
plugins, ActiveX controls
–Block third-party cookies
 Attackers use phishing emails
as the entry point of attack

10. 8. Malware Defenses
 Control the installation and
spread of malicious code
 Attackers can use
malware to attack target
organizations via number
of entry points like end-
user devices, email
attachments and web
pages

11. 9. Limitation and Control of Network Ports and Services
Manage and track the use
of ports, protocols and
services
Attackers are continuously
searching for remotely
accessible network services
and open ports

12. 10. Data Recovery Capability
 Backup critical information
 When attackers compromise
systems
– Make significant changes to
configurations of software
– Make alterations of data
 When discovered, need to
remove all data that have
been altered by attackers
