CISO's first 100 days
- 1. BY DESIGN, NOT BY CHANCE CISO’S FIRST 100 DAYS Michael A. Sadeghi, Ph.D. ABD, CISSP
- 2. AN IMPORTANT GOAL FOR TODAY’S PRESENTATION
- 3. WHAT WE COVER TODAY • Some Infosec facts and statistics • Key questions for Senior leadership • Defining the “CISO” terminology • 360 deg. View of the role • First 100 days roadmap • Final thoughts
- 4. SOME STATISTICS (2018 VERIZON AND WTO REPORTS) • The cost of cyber intrusion damage is estimated to be about a Trillion dollars/Yr and increasing. As a comparison, the cost of all natural disasters in 2017 was $300 Billion • Economic cost of a major cloud provider taken down is about $50-120 Billion • Equivalent to the Sandy to Katrina hurricane damages!!! • In 87% of cases, attackers are able to compromise an organization within minuets. 68% go undiscovered for months or more! • 75% of attacks spread from Victim 0 to Victim 1 within 24 hours • Organized Cybercriminals were behind 50% of all the breaches • You have 16 min until the first click on the phishing campaign • Insider attacks are particularly difficult to defend against
- 5. KEY QUESTIONS TO ASK • How can you detect a compromise? • How do you judge the severity of the compromise? • What is the impact of the compromise to your organization? • Who is responsible for detecting and reacting to the compromise? • Who should be informed or involved, and when do you deal with a compromise when its detected? • How and when should you communicate a compromise internally or externally? (Note, sometimes engaging authorities is required by law.)
- 6. BROAD STROKES • Good news • Most typical threat vectors are well understood and are defended against! • Rising tide has raised the average IT and information security implementation • Bad news • If you are a targeted industry, the attack vectors are much more extreme and hard to defend against! • DoD and Intel, Research and development organizations, HHS, FDA, Medical, etc. • Its not a question of IF but WHEN a major breach will occur.
- 7. DEFINING THE CISO TERMINOLOGY • Traditional vs. Other/Alternative? • Difference is in sufficient responsibility and authority • Wikipedia definition – Key takeaways • Senior level executive, Responsible for enterprise vision, strategy and program, to insure information assets and technologies are adequately protected. • Typically CISO’s influence reaches the entire organization • Responds to Incidents, Establish standards, Manage security technologies, and Direct implementation of policies and procedures
- 8. CISO CAN COME IN DIFFERENT “FLAVORS” Traditional • Most senior manager specifically dedicated to InfoSec • Is no more than two steps away from the CEO • Has a staff of SMEs covering each of the areas of the responsibility • Alternative/Other • Scope may be limited to a division, business unit or geography • May be a collateral duty • May be buried deeper in the hierarchy • Key question – Is this a Traditional or Alternative role

- 13. ASSESS Gain comprehensive insight • Commitment of the leadership to the security effort – involved vs committed • In a Ham and Egg breakfast, Egg is involved and Pig is committed • Compile a list of the stakeholders and involvement – Maybe a long list • Cybersecurity Posture • Identify the business and IT goals • Identify people, metrics, technology and financial parameters • Which security initiatives have been implemented in the last few years? • Has organization experienced any cyberattack or date breaches?

- 20. EXAMPLE OF MATURE SOC W. LAYERED SECURITY, NETWORK SEGMENTATION, AND MONITORING TECHOLOGIES
- 21. INTERNAL SOC ADVANTAGES DISADVANTAGES • Dedicated staff • Larger up-front investments • Known environment, better than third party • Higher pressure to show ROI quickly • Solutions are generally easier to customize • Higher potential for collusion between analyst and attacker • Potential to be most effective • Less likely to recognize large-scale, subtle patterns that include multiple groups • Most likely to notice correlations between internal groups • Can be hard to find competent SOC analyst • Logs stored locally
- 22. OUTSOURCED SOC ADVANTAGES DISADVANTAGES • Avoid capital expenses – It’s their hardware and software • Contractors will never know your environment like internal employees • Exposure to multiple customers in similar industry segments • Sending jobs outside the organization can lower morale • Often cheaper than inhouse • Lack of dedicated staff to a single client • Less potential for collusion between monitoring team and attacker • Lack of capital retention • Good security people are often difficult to find • Risk of external data mishandling • Unbiased • Log data not always archived • Potential to be very scalable & flexible • Log data stored off-premises • Expertise in monitoring and SIEM tools • Lack of customization • SLA

Hinweis der Redaktion
- Security defenses must expand across all areas of the network. If you don't provide the same level of security for the various parts of your network, the least-protected area will most likely be targeted by malicious parties for attack. Design areas included are securing the network edge, mobile devices, user desktops, branch offices, and the datacenter.
