3 IT Security Update on Practical Risk Mitigation Strategies Learning Objectives/Knowledge Gained IT Security Update on 2016 Threats McAfee Labs 2016 Threat Predictions PwC 2016 Forecast Cybersecurity events - what they have in common Practical Risk Mitigation Strategies Increased knowledge of cybersecurity risk assessment processes and tools IT controls to mitigate risks Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 3

4 McAfee Labs 2016 Threat Predictions Threat Hardware Ransomware Vulnerabilities Payment Systems Comments Operating System level attacks As a service hosted on the Tor Network Financial and Government sectors targets Targeting cloud services and mobile devices Abode Flash, Unix Credential stealing and attacking payment card devices (skimmers, etc) Elliott Davis Decosimo, LLC 4

5 McAfee Labs 2016 Threat Predictions Threat Attacks through Employee Systems Cloud Services Integrity Comments Increase expected in Android devices. Securing home networks for employees remote access. Users have little insight into the provider s security measures Compromise the integrity of the systems and data. Stealth, selective, attacks appearing to be operational problems, accounting errors, or dumb mistakes, Elliott Davis Decosimo, LLC 5

6 PwC Survey - Top 3 Challenges - Financial Services Financial services respondents ranked assessment of security capabilities of third-party vendors as the top challenge to their information security efforts. More than half said they would increase spending to better monitor third-party security in the coming 12 months. Average information security spending is up 15% 2. Rapidly evolving, sophisticated, and complex technologies 3. Increased use of mobile technologies by customers Elliott Davis Decosimo, LLC 6

7 Cyber Security Events What They Have in Common Social Engineering Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 7

8 Social Engineering Defined Social Engineering, in the context of information security, refers to psychological manipulation of people into performing actions or divulging confidential information. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in that it is often one of many steps in a more complex fraud scheme Elliott Davis Decosimo, PLLC

9 Common Data Breaches/Threats Phishing is a form of social engineering Phishing is the most common threat Usually accomplished through or phone call schemes Our employees are our weakest link Continuous/annual employee training is a must in this area to assist with prevention Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 9

10 Spear Phishing Unlike traditional spam, spear phishing is by no means random it is a highly-targeted operation. Sender impersonates a friend or colleague of potential victims in order to trick them into opening malware-ridden files or into visiting malicious websites, or do some action for the phishers benefit Has a high success rate Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 10

Malware creates backdoor access for cyber criminal) 66% Captured Stored Data (Ex. Ransomware) 55% Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 12

15 1 - IT General Controls Security Administration Logical Security Change Management Operations User provisioning Password controls Authorization and Approval Backups User removal Privilege User review User Testing Restore test User Access Reviews/with SoD Elliott Davis Decosimo, LLC Elliott Davis Decosimo, PLLC 15 Security Monitoring Physical Access to Production Segregation of Duties Vendor Management Job Monitoring

16 2 - Cyber Security Assessments Internal Network Vulnerability Scans Patching is largest category System configuration External Network Vulnerability Scans External Penetration Testing Wireless Scans Social Engineering Assessments Social Engineering Training Elliott Davis Decosimo, LLC 16

17 2 - Cyber Security Assessments Reporting Categories Category Patch Management Vulnerabilities Resulting from. Failure to apply patches provided by vendors to address security weaknesses. Software / firmware patches are primarily an administrative detail. System Configuration Trust Application Elliott Davis Decosimo, LLC Identified configuration settings on devices that may not be set in an optimal manner for security consideration. Identification of insecure authentication methods or configurations on workstations/servers. Discovery of applications with known vulnerabilities found on the network. Examples include the discovery of software such as Dropbox, Skype, and Coupons Printer. 17

18 3 - Training - Employee and IT Specific Training, training, training (employees as well as clients/customers) Technical training for key employees and management Set the appropriate tone at the top make security a priority and not just an IT initiative Elliott Davis Decosimo, LLC 18
