Is there such thing as ethical hacking? A hacker exploits weaknesses in a

computer system. Hacking or cracking which refers

to unauthorized access into orinterference in a computersystem… (RA 8792, E-CommerceLaw)

Someone with an advancedunderstanding of computers andcomputer networks… (A Guide tothe World of Computer Wizards)

Ex. Hacking with a Pringles tube(from BBC News)

What separates good from bad hackers? They both exploit weaknesses in a computer system or

network. The difference is – permission

and scope.

White hat – good guys Black hat – bad guys Gray hat – good in the morning; bad in the evening

With this definition, what’s the classification ofAnonymous?

Reconnaissance Observation Research about your target Start from online tools Netcraft Archive Web Data Extractor

Job opportunities

Observation Research about your target Start from online tools Netcraft Archive Web Data Extractor

Scanning Look for open

opportunities nmap, hping

Firewalking

Gaining & Maintaining Access Password Guessing Privilege Escalation Executing Malicious Codes Copying files

What is information security?What is information security?

What is information security? Protection of information systems against unauthorized

access to or modification of information, whether instorage, processing or transit, and against the denial ofservice to authorized users or the provision of service tounauthorized users, including those measures necessaryto detect, document, and counter such threats. (U.S.National Information Systems Security)

The CIA triad

The CIA Triad explained Confidentiality – Protection against unauthorized access. Integrity – Protection against unauthorized modification. Availability – Protection against Denial of Service (DoS)

Examples:

Remember the 3-way handshake!

Information Security vs. IT Security Information Security has many domains. Access control, telecommunications and network security,

Information security governance and risk management,Software development security, Cryptography, Securityarchitecture and design, Operations security, Businesscontinuity and disaster recovery planning, Legal, regulations,investigations and compliance, Physical (environmental) security– from CISSP’s domains on ISC2

IT Security only focuses on software and hardwaretechnologies.

Defense in Depth

Definition of Protection Past & Present PROTECTION = PREVENTION

Example: Gate, Network Firewall

Problem: What if the thief climbs over the gate? Problem 2: What if there is a DoS attempt in a web

server on port 80.

INCIDENT RESPONSE)

Example: Motion detector tools, anti-virus for host device,Intrusion Detection System (IDS) for network.

Reality Check You cannot eliminate all risks. You do not have a lot of money to buy all controls to

mitigate the risks. You need to prioritize.

Least Privilege A user/program must be able to access only the

information and resources that are necessary for itslegitimate purpose.

It is the essence of all domains in information security

Separation of Duties (SOD) The concept of having more than one person required to

complete a task. Keys to the kingdom Example: How payroll is computed, approved, delivered

etc.

Policies HR Policies Clean desk policy Acceptable Use Policy Internet policy Data security policy Password Policy

Physical Security Natural barriers Authentication (something to you know, something that

you have, something that you are) Gates and dogs Guards

Network Security Firewalls Intrusion Detection Systems (IDS) Unified Threat Management (UTM) Data Loss Prevention (DLP)

Host Security Port Security Anti-virus User access (standard, admin, super admin)

Application Security Encryption Patches, hotfixes

What issues need to be addressed?What issues need to be addressed?

Focus on 2 critical issues Social Engineering Web Application Attacks

Social Engineering Social engineering is the hacker/attacker's clever

manipulation of the natural human tendency to trust toobtain information that will allow him to gainunauthorized access to a valued system. (SocialEngineering Fundamentals)

90% of successful hacking activities are done using socialengineering.

Steps in Social Engineering Information Gathering Stalk in social networking sites Mail-outs Forensic analysis Facebook apps

Developing Relationships Cognitive biases (returning the favor, share interests)

Exploitation People become less reasonable when in state of shock or

strong affect.

Types of Social Engineering Attacks Physical Shoulder surfing Dumpster diving (ex. Argo) Tailgating War driving, chalking, walking

etc.

Online Phishing Pharming Spear phishing Vishing

Countermeasures Create, implement and harden security policies People easily forget policies. It needs enforcement.

Comply with physical security standards Are doors locked? Do security guards check all students for

ID?

Security Awareness Training for employees This should be done periodically.

Resistance Training for specified employees Social Engineering Land Mines (SANS, David Gragg) Call-back policy, key questions, bogus questions

Incident Response

Web Application Attacks A lot of people are using the Internet and doing

transactions there. A lot of websites are not checked whether it is safe for

users to use. It’s possible that applications follow proper coding

standards but versions/functions are vulnerable.

Usual attacks: SQL Injection Cross Site Scripting (XSS) Session Hijacking Directory Traversal Cross Site Request Forgery (CSRF)

Web Application Security Advice Include security in all SDLC steps. Refer to the Open Web Application Security Project

(OWASP) when writing web applications.https://www.owasp.org/

Use both source code analyzer and vulnerability scannerto check the status of your application.

Information Security as a DisciplineInformation Security as a Discipline

Information Security as a Discipline InfoSec is a relatively new field. It is starting to grow because a lot of businesses are

transitioning to online. Virtual money is same as physical money. There are still few professionals who are in this field. Supply is low, demand is high. CS and IT major courses are good infosec foundations. You can opt to choose infosec in thesis.

Do we need a cybercrime law?Do we need a cybercrime law?

Do we need a cybercrime law? Of course, we need one. R.A. 10175 or Cybercrime Prevention Act is a mixture of

several issues. Cybercrime Law should not only focus on the limitation

of Freedom of Expression. Cybercrime Law should protect the people.

What kind of cybercrime law do we need? A law that compels for-profit organizations like banks to

follow certain best standards to protect client data foundin bank accounts.

A law that compels telecom companies to ensure thatdata that pass their infrastructure are sent and receivedto the intended recipients.

A law that compels government offices to securely storepersonal data that are found in their computer system.
