The Big Picture
What are we hoping for when we say
we want our network to be secure?
• No interruptions to operations?
• No data loss?
• No inappropriate use of IT resources?
We are focused on the traditional view in
this webinar. For our purposes today:
IT Security means preventing unauthorized
access, misuse, modification or denial of IT
resources.(credit to Wikipedia)
What are your organization’s biggest IT
security challenges?
Poll question
Denial of Service attack prevents access to our
organization’s website for six hours.
Malware causes half my desktops to participate in a
“bot army.”
Interns are reading the personnel files of veteran staff
members.
The office manager is using your organization’s fantastic
Internet connection to download copyrighted movies
so he can burn them to DVD and watch them at home.
Examples
Organizational
Philosophy/Attitude
What is your organizational
balance between security,
accessibility and cost?
• What is your mission?
• Who do you serve?
• What types of data do you have?
• How many users?
• What does your existing security infrastructure look like?
Assessing your organization’s risk
• Where do your users do most of their work?
• Do they use their own devices?
• Do they need remote access to your systems?
What are your accessibility
requirements?
• What is required by law or credentialing
organizations?
• What is the state of your current network?
• What is your IT budget?
What is the cost of security?
Organizational Structures
• Does your organization think about security?
• Are user accountable for their actions?
• Do stakeholders understand what security breaches can mean for the mission?
Security Culture
• Office Manager?
• HR person?
• CFO?
Someone needs to “own” security
Who is responsible for IT Security in your
organization?

• Can provide VPN remote access.
• Replace every 5 years.
• Size appropriately.
• Maintain your firewall (update firmware, backup, maintain support contract, remove policies when no longer in use).
Firewalls
• Hosted is preferred.
• Mail Continuity service can be included.
• Postini was great.
• Community IT offers McAfee SaaS Email
Protection and Continuity to its clients.
Email Filters
• You must have it. You must maintain it.
• An enterprise solution is needed (includes centralized management).
• Cloud-based is preferred so that traveling laptops have access to updated definitions whenever they are online.
• No solution is immune to the zero-day threat.
• Community IT offers Vipre Antivirus to its clients.
• AV software is no substitute for careful end user behavior
Desktop/Server Antivirus Software
• Popular in school and lab scenarios.
• Doesn’t have to restrict access to content
areas.
• No substitute for good end user habits.
Internet Content Filtering
• Not something our clients are doing at
the enterprise level.
• Overhead – password/recovery system
needed.
• Can be circumvented.
File/Disk Encryption
• Hosted services are coming online, very
much a work in progress.
• Allows focus on maintaining a single
complex frequently changed password.
• Builds corporate ownership of distributed
hosted services.
Single Sign-On
• Two separate authentication systems
must be navigated to gain access –
famous example is the ATM machine.
• Google offers 2-factor authentication to
Gmail (and other Google apps).
• Key fobs replaced by “soft tokens” on
mobile phones.
Two Factor Authentication
• Mobile devices have become a
significant data leakage/loss
opportunity.
• Can conflict with BYOD expectations.
• On Community IT’s service offering road
map.
Mobile Device Management
End User Responsibility

need to improve on the most?
