Simplifying the data privacy governance quagmire building automated privacy ...Avinash Ramineni
In this age of big data, AI, and machine learning, organizations collect vast amounts of data about their customers, processes, preferences, usage patterns, etc. Organizations intend to use the data and generate a sustained competitive advantage for their products/offerings.
With all the data they are collecting and storing, they also accumulate huge risks associated with storing and protecting the data. Balancing monetizing data with the risk puts a lot of the roles like CDO, CPO, CISO, CIO in a quagmire.
Privacy / Security leadership needs to influence the organization in adopting a privacy/security-first culture by establishing a robust privacy/security program. Most organizations need to be able to achieve that within a limited budget.
Ideally, at the end of the rollout of a privacy program, a company can tell:
Where every bit of sensitive data resides,
Who has access to which sensitive data,
All security controls to protect sensitive data, and
The retention times for every piece of sensitive data.
In this webinar, we will cover how to build a dynamic and automated privacy/security program that manages the data lifecycle from collection to deletion. This talk will also give a sneak peek into technologies that will influence the privacy, security, governance capabilities of the future and reshape the way organizations address challenges with current and emerging technologies.
What you’ll take away:
Basic concepts around understanding the risk around the personal information your organization is collecting
Building a method of mitigating the risk discussed above
how to incorporate an enterprise-wide ‘security-first’ culture
A practical approach to implementing a data privacy/security program from scratch.

Security Information and Event Management (SIEM) is software that combines security information management (SIM) and security event management (SEM). It collects logs from network devices, applications, servers and other sources to detect threats, ensure compliance with regulations, and aid investigations. Key features of SIEM include log collection, user activity monitoring, real-time event correlation, log retention, compliance reports, file integrity monitoring, log forensics, and customizable dashboards. SIEM solutions can be deployed in various ways including self-hosted, cloud-based, or as a hybrid model managed by the organization or a managed security service provider.
Here are the key advantages and disadvantages of single sign-on (SSO):
Advantages:
- Convenience - Users only need to remember one set of credentials to access multiple systems and applications. This improves user experience.
- Increased security - SSO reduces the risk of phishing and password theft since users are not entering credentials repeatedly. It also allows for stronger, centralized authentication policies.
- Lower costs - SSO reduces the overhead of user provisioning and password management across multiple systems. It streamlines IT operations.
Disadvantages:
- Single point of failure - If the SSO server goes down, users cannot access any of the linked systems until it is restored. This reduces availability.
- Increased
Network security is important for protecting companies and users from various threats. There are many types of network security attacks, including malware, social engineering, and insider threats. These attacks can have major impacts on companies like reduced transactions and stock prices following breaches. Strategies to improve security include using VPNs, cryptography, firewalls, intrusion detection systems, and penetration testing. With greater awareness and education, network security benefits companies through enhanced reputation and protection of valuable information.
The document discusses identity and access management strategies for defending against advanced persistent threats (APTs). It outlines how APTs typically progress through four phases - reconnaissance, initial entry, escalation of privileges, and continuous exploitation. It then proposes a "defense-in-depth" approach using identity and access management capabilities to make initial penetration difficult, reduce privilege escalation, limit damage from compromised accounts, and aid in early detection and forensic investigation. Specific capabilities discussed include identity governance, least privilege access, shared account management, session recording, server hardening, and advanced authentication.
Computer networks connect devices through communication systems. Network security aims to protect information and allow authorized access. It involves authentication of users, monitoring network traffic for intrusions, and other strategies. Intrusion detection systems monitor for suspicious activity and notify administrators. There are different types of intrusion detection including network-based and host-based systems. Penetration testing evaluates security by simulating attacks. Cryptography also helps secure networks through techniques like public key encryption, hashing, and key exchange algorithms.

Editor's Notes
We organize information security solutions into six classes: security management, cryptography, access control, data traffic control, security analysis, and physical security.
Sophisticated computer management systems, called system controllers, have been around for decades. This units were hooked up in mainframes in data centers.
OpenView has built-in IP network management standard Simple Network Management Protocol (SNMP).
ESM: fuziness in the area separating networks and computers from the development of the client-serve technology that moved data from data centers to internetworking topology.
Symmetric Algorithm main parts are:
Plaintext
Encryption Algorithm
Secret Key – the main secret
Cipher Text
Decryption
Modern symmetric block encryption algorithms are mainly based on the Feistel block cipher structure. Feistel proposed the use of a cipher that alternates substitutions and permutations. In fact, this is a practical application of a proposal by Claude Shannon to develop a product cipher that alternates confusion and diffusion functions.
Diffusion, when each cipher text digit is affected by many plaintext digits.
Confusion, when the relationship between the statistics of the cipher text and the value of the encryption key is as complex as possible.
Block ciphers include DES, IDEA, SAFER, Blowfish…
Also I would like to mention that the Skipjack -- this last being the algorithm used in the US National Security Agency (NSA) Clipper chip, used for U. S. government's Escrowed Encryption Standard (EES), is block cipher.
Intranet VPN
This is considered "client transparent" VPN. It is usually implemented for networks within a common network infrastructure but across various physical locations. For instance several buildings may be connected to a data center, that they can access securely through private lines. Those VPNs need to be especially secure with strong encryption and meet strict performance and bandwidth requirements.
Remote Access VPN
Here VPN is "client initiated". It is intended for remote users that need to connect to their corporate LAN from various point of connections. It is intended for telecommuters and salesmen equipped with laptops that connect intermittently from different locations (homes, hotels, conference halls...). The key factor here is flexibility as performance and bandwidth are usually minimal and less of an issue. More than encryption, authentication will be the main security concern.
Extranet VPN
In this case VPN uses the Internet as main backbone. It usually addresses a wider scale of users and locations, enabling users to access corporate resources across various network architectures. They rely on VPN standards to ensure maximum compatibility while trying not to overly compromise security.
Computers can use the PPTP protocol to securely connect to a private network as a remote access client by using a public data network such as the Internet. In other words, PPTP enables on-demand, virtual private networks over the Internet or other public TCP/IP-based data networks. PPTP can also be used by computers connected to a LAN to create a virtual private network across the LAN.
PPTP is configured by adding virtual devices referred to as virtual private networks (VPNs) to the RAS and Dial-Up Networking.
Most PPTP sessions are started by a client dialing up an ISP network access server.
The Point-to-Point Protocol (PPP) is a data link layer protocol which encapsulates other network layer protocols for transmission on synchronous and asynchronous communication lines.
Two precise definitions of "point-to-point" in the context of data communications follow:
A network configuration in which a connection is established between two, and only two points. The connection may include switching facilities.
A circuit connecting two points without the use of any intermediate terminal or computer.
The PPP protocol is used to create the dial-up connection between the client and network access server and performs the following three functions:
Establishes and ends the physical connection. The PPP protocol uses a sequence defined in RFC 1661 to establish and maintain connections between remote computers.
Authenticates users. PPTP clients are authenticated by using the PPP protocol. Clear text, encrypted, or Microsoft encrypted authentication can be used by the PPP protocol.
Creates PPP datagrams that contain encrypted IPX, NetBEUI, or TCP/IP packets . PPP creates datagrams which contain one or more encrypted TCP/IP, IPX, or NetBEUI data packets. Because the network packets are encrypted, all traffic between a PPP client and a network access server is secure.
Layer Two Tunneling Protocol (L2TP) is a combination of PPTP and Layer 2 Forwarding (L2F), a technology proposed by Cisco® Systems, Inc. Rather than having two incompatible tunneling protocols competing in the marketplace and causing customer confusion, the IETF mandated that the two technologies be combined into a single tunneling protocol that represents the best features of PPTP and L2F. L2TP is documented in RFC 2661.
Access control techniques
Access control techniques are sometimes categorized as either discretionary or non-discretionary. The three most widely recognized models are Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role Based Access Control (RBAC). MAC and RBAC are both non-discretionary.
(DAC) is an access policy determined by the owner of an object. The owner decides who is allowed to access the object and what privileges they have.
(MAC) is an access policy determined by the system, not the owner. MAC is used in multilevel systems that process highly sensitive data, such as classified government and military information. A multilevel system is a single computer system that handles multiple classification levels between subjects and objects.
(RBAC) is an access policy determined by the system, not the owner. RBAC is used in commercial applications and also in military systems, where multi-level security requirements may also exist. RBAC differs from DAC in that DAC allows users to control access to their resources, while in RBAC, access is controlled at the system level, outside of the user's control. Although RBAC is non-discretionary, it can be distinguished from MAC primarily in the way permissions are handled. MAC controls read and write permissions based on a user's clearance level and additional labels. RBAC controls collections of permissions that may include complex operations such as an e-commerce transaction, or may be as simple as read or write. A role in RBAC can be viewed as a set of permissions.
The principle of least privilege states that only the minimum access necessary to perform an operation should be granted, and that access should be granted only for the minimum amount of time necessary.
Network firewalls protect the perimeter of a network by watching traffic that enters and leaves.
An application firewall is a form of firewall which controls input, output, and/or access from, to, or by an application or service. It operates by monitoring and potentially blocking the input, output, or system service calls which do not meet the configured policy of the firewall.
Stateful firewall (any firewall that performs stateful packet inspection (SPI) or stateful inspection) is a firewall that keeps track of the state of network connections (such as TCP streams, UDP communication) traveling across it. The firewall is programmed to distinguish legitimate packets for different types of connections. Only packets matching a known connection state will be allowed by the firewall; others will be rejected.
A penetration test is a method of evaluating the security of a computer system or network by simulating an attack from a malicious source.
The process involves an active analysis of the system for any potential vulnerabilities that could result from poor or improper system configuration, both known and unknown hardware or software flaws, or operational weaknesses in process or technical countermeasures. This analysis is carried out from the position of a potential attacker and can involve active exploitation of security vulnerabilities.
External testing(Black box) refers to attacks on the organization's network perimeter using procedures performed from outside the organization's systems, that is, from the Internet or Extranet.
Internal testing (White box) penetration test evaluates the efficacy of a network’s internal protection. Network configurations, source codes and the occasional password are provided in the white box penetration test.
Security controls in the security control catalog (NIST SP 800-53, Appendix F) have a well-defined organization and structure.
The security controls are organized into classes and families for ease of use in the control selection and specification process.
There are three general classes of security controls (i.e., management, operational, and technical18). Each family contains security controls related to the security function of the family. A standardized, two-character identifier is assigned to uniquely identify each control family. Table summarizes the classes and families in the security control catalog and the associated family identifiers.
An agency has the flexibility to tailor the security control baseline in accordance with the terms and conditions set forth in the standard. Tailoring activities include:
(i) the application of scoping guidance;
(ii) the specification of compensating controls;
(iii) the specification of agency-defined parameters in the security controls, where allowed.
The system security plan should document all tailoring activities.
