Cybersecurity Essentials: Identity and Privacy

In the vast and noisy digital universe we live in, managing online identities and all aspects related to digital privacy has become (pun not intended…) essential.

While the approach might not be immediately straightforward, and kind of scary for non-experts, we will try to explore in detail important concepts such as digital identities, authentication, authorization, and password management… also going through an understanding of tools and best practices, trying to touch on the points that generate the most interest and require more attention in such sensitive areas.

In other words, we will address those aspects of our digital life that are covered by the Linux Professional Institute (LPI) Security Essentials Exam (020) objectives.

Digital Identity

What do we mean by digital identity?

Let’s start with understanding what identity means online. Each online individual is characterized by a unique set of information. This identity includes data such as name, email address, phone numbers, and other personal information that identifies a user in the digital world. We can consider this online identity as a virtual representation of an individual’s real identity… therefore, one’s digital identity is a unique key to access all public services and the services of private companies that intend to use this widespread recognition system.

Among these concepts we can include some social networking tools that can also be used for the aforementioned purposes, to strengthen the concept of this “new identity” that has been virtualized on the web.

Now let’s list some absolutely fundamental points about how to behave correctly without risking all our important activities.

Authentication, Authorization, and Accounting

To ensure the security of digital identities, it is crucial to understand these concepts:

◉ Authentication verifies a user’s identity.

◉ Authorization controls access to resources based on assigned permissions.

◉ Accounting documents and stores user information, particularly about attempts to access resources.

A fundamental aspect of identity management is access control, namely the ability to control who has access to the network, what they can do, and what services they can use after logging in.

Often going by the abbrevation AAA, the concepts of authentication, authorization, and accounting refer to a framework through which access to the network or the resources concerned can be configured. Authentication identifies users through methods such as logging in with a password or smart card. Authorization provides access control based on the profile with which the user authenticated, and is based on a set of attributes that describe the rules associated with that particular user. Accounting, finally, tracks a user’s activities, such as the services used and network resources consumed.

Often, administrators want users who belong to a certain organization to have access to services of other structures that are part of a common federation. For instance, a business might be federated with another company that handles payroll. To enable a federation, organizations must share mechanisms for exchanging user information and for managing access to federated resources.

The term federation, therefore, means an arrangement between organizations and resource providers that specifies a mutual trust agreement, as well as the information they exchange in the processes of authentication and authorization, based on rules that manage these trust relationships.

The main task of the federation is to keep all the resources in the federated organizations available to the different users who are part of them. Access management at the federation level means managing identities and accesses among a set of organizations.

Secure Passwords

Passwords represent one of the key elements of online security. A secure password must have characteristics such as sufficient length, the use of special characters, high complexity, and regular, frequent replacement. Understanding these characteristics is essential to protect online accounts. To maintain a high level of entropy of the passwords used, it is recommended to use a length greater than 8 characters, not to use more than 2 identical consecutive characters, and to avoid names of things or known names, preferring instead a set of entirely random alphanumeric characters. It is recommended to change passwords every 3 months and never to use the same password for different services or online accounts.

Use of a Password Manager

A fundamental step towards password security is the use of a password manager. These tools generate, store, and manage complex combinations of passwords for various online accounts securely and simply, significantly simplifying the management of digital identities. A well-known example is KeePass, a password management tool under the GNU GPL license.

Multi-Factor Authentication (MFA) and Single Sign-On (SSO)

The concepts of two-factor and multi-factor authentication (2FA and MFA) add an additional layer of security by requiring more than one form of verification, typically added to the classic login with username and password. Single sign-on (SSO) allows access to multiple services with a single authentication that is considered valid and is trusted.

Online Transaction Security

Everything we have seen previously helps us understand online transaction security, which includes safe practices for online banking, credit card management, access to public services that contain private personal information, online purchases on various platforms, and so on.

Awareness of possible threats and the practice of security measures can protect against fraud, unauthorized access, and other web threats. Safely navigating the digital world requires an in-depth understanding of concepts of digital identity, authentication, password security, and all other related aspects of protecting one’s online presence. By implementing the recommended practices and tools, it’s possible to protect one’s online presence and effectively face the challenges of digital security. Awareness is the key to a safe and responsible digital experience, for us and the entire community.

A Crash Course in Cryptography

There are many fascinating topics in the universe of Information Security, but if I had to place one above all others (this being a purely personal opinion), Cryptography would occupy the highest level.

This topic has its deepest roots in pure mathematics, but now touches many areas of technology in the daily lives of thousands of people… so much so that in many cases its presence is taken for granted. It is present on multiple levels and is the key that guards our electronic secrets.

But…What is cryptography?

Symmetric and Asymmetric Cryptography

Cryptography is a method to encode content in a format that is impossible to read for those who are not authorized to do so. It is composed of a series of technologies that, together, keep data safe. The term encryption is roughly synonymous with cryptography.

The original text, which is readable by anyone, is called clear text or plain text. Encryption produces encrypted text.

When using unprotected connections, without a proper encryption protocol, it is relatively easy for a snooper to steal personal information by seeing data in transit in the clear. For instance, if you sit in a café and send email over a connection that is not protected by cryptography, the person on a computer at another table could pick up your traffic and ready your email.

We can categorize the various types of cryptography as either symmetric or asymmetric.

Symmetric cryptography uses the same, single secret key to encrypt the clear information and to decrypt it. If the text is being transmitted between people both the sender and the receiver use the same key.

In practice, the sender encrypts the message with a secret key, then transmits the message through a communication channel. The recipient receives the message and decrypts it with the secret key. The recipient normally receives the key from the sender through a predefined, safe transmission channel–not the same channel used for the message, because by definition that channel is assumed to be viewable by attackers.

The keys represent a shared secret between the parties, which can be used to maintain a private link of information.

Symmetric cryptography is relatively simple (although the mathematics used to create the key is very sophisticated), easy to implement, and has good overall performance.

Among the algorithms that support symmetric cryptography we find:

◉ DES

◉ 3DES

◉ AES

Among these, AES is currently the most modern and robust, and is commonly used for very sensitive information, even by government bodies.

Asymmetric cryptography, also known as public key cryptography, encrypts and decrypts data using two distinct keys. These two keys are named the “public key” and the “private key.” The public key can be distributed wherever the sender wants a message to be readable, whereas the private key must be kept, of course, secret.

If either of the two keys encrypts the message, it can be decrypted only with the other key.

Asymmetric cryptography is significantly slower than its symmetric counterpart, because the keys are longer and the related calculations to be performed are much more complex.

The exceptionally long length of the keys in use makes it practically impossible to derive private keys from the associated public keys, even though they are mathematically linked by the calculation that produced them both.

Because the public key can be safely transmitted over a channel where attackers can grab it, asymmetric cryptography is often used to exchange the secret key used later for symmetric cryptography.

Some of the algorithms that support asymmetric cryptography are:

◉ El Gamal

◉ Diffie Hellman

◉ RSA

RSA, given its ease of use and its intrinsic robustness, which stems from computational entropy, is the preferred algorithm for encrypting and signing messages.

Public Key Infrastructure (PKI)

Asymmetric keys introduce another fundamental infrastructural concept in the matter of encryption: Public Key Infrastructure (PKI).

PKI is a sequence of processes and tools that allow authoritative third parties “in trust” to determine the identity of a user and to verify that a public key legitimately belongs to that user.

The impetus behind PKI is that, when users make initial contact online—such as by logging into a retail web site—they don’t know whether they are reaching the real person or company they want. A malicious “man in the middle” attacker could claim to be a major retail site, and an encryption key by itself cannot guarantee that the legitimate site is the one sending the key.

To provide the trust necessary for Internet communication among parties who don’t previously know each other, PKI registers identity of at least one party.

Identities are defined in a digital public key certificate with a standard called X.509.

A site called a Certification Authority (CA), which is recognized and trusted by both side, creates digital certificates that securely tie sites to their public keys. Web users generally trust CAs because the CAs’ identities are hardcoded into the user’s browser.

The implementation of PKI can be found, for example, in contexts such as:

◉ Certificates for websites

◉ Private networks and VPNs

◉ Cloud applications and services

◉ Email security

◉ User and device authentication

◉ Signing of documents and messages

Uses for Cryptography

You should now have a rough idea of cryptography and its value. Here we’ll look at different contexts for using cryptography:

◉ Email

◉ Web browsing

◉ Data storage

Email

The main email encryption protocols are S/MIME and PGP/MIME.

S/MIME, which stands for Secure/Multipurpose Internet Mail Extensions, is integrated into most devices and uses a centralized CA to determine the encryption algorithm and keys to be used. S/MIME is primarily used in large Web-based email platforms.

PGP/MIME, which stands for Pretty Good Privacy/Multipurpose Internet Mail Extensions uses a decentralized authority model. In contrast to S/MIME, key management is not governed by a CA, but is more the responsibility of the user. Users rely on a “web of trust” to establish the authenticity of the user on the other side of the communication.This protocol depends on of third-party encryption software.

PGP/MIME is proprietary. A free re-implementation, GnuPG (also called GPG), performs the same task without major differences.

Web browsing

A user establishes an encrypted connection to a website by entering or clicking on a URL starting with HTTPS instead of HTTP. HTTPS is a hypertext transmission protocol that additionally is secure because all traffic sent over the Internet is encrypted. Therefore, when a connection is based on HTTPS, privacy and integrity of data are guaranteed.

HTTPS is the successor to HTTP, which transmits date in plain text and has been gradually deprecated (except for a few rare use cases).

The HTTPS protocol integrates HTTP with the TLS cryptographic protocol (a successor to another protocol for web encryption, SSL), adding a valid digital certificate. SSL and TLS are essentially the same protocol that has evolved over time, with TLS being the most modern format and now in version 1.3.

Browsers that send and receive data over secure HTTPS often display a green lock.

Data storage

Data can be encrypted at multiple levels: not just in transmission when email or the Web are used, but also locally on storage devices such as hard drives, USB drives,and tape drives.

The use of storage-side or file-side encryption greatly offsets the risk of data loss. Like encryption used on the network, storage-side encryption is a very powerful tool that protects all data on every device, regardless of the type of physical media, interface, or data privacy class.

Storage-side encryption is a great way to ensure data security, especially if the device is stolen.

Linux users can keep data safe through Linux Unified Key Setup (LUKS). It employs a brute force encryption algorithm and totally secures data if a strong password is used. LUKS is currently in version 2.

Newer Linux distributions also offer full disk encryption (FDE) at the end of operating system installation, setting a strong password to control access to the contents of the disk. But be careful and don’t forget your password: When data is encrypted on the disk using full disk encryption, if the password is lost the data inside will be very difficult to recover.

Absolute security is a pipe dream, but to paraphrase J. W. von Goethe, “He who wants to take sure steps must walk slowly.”

A Tech Trainer Discovers the Security Essentials Certification

More than a decade ago, while preparing to take my very first technology certification exam (the LPIC-1, as it happened), I learned something new about the entire certification process. Now, I was no stranger to the education world at that point: I'd been a high school teacher and administrator for the previous twenty years. But slowly working through the long list of Linux administration objectives made me realize that all the hard work was less about the exam and more about making sure I was competent in the skills and tools I'd need as a Linux admin.

IT professionals are often responsible for protecting millions of dollars of equipment and critical business processes. Keeping ahead of all the nasty things that are waiting to land is hard enough for even the best of admins. But where are "the best of admins" supposed to learn their trade? I'm aware of no college specializations or even boot camps that teach IT administration. You could learn the skills you'll need through the painful experience of recovering from expensive mistakes. Or you can work through a well-designed certification curriculum, which is what LPI offers. 

When I agreed to write the Wiley/Sybex book "The LPI Security Essentials Study Guide" along with my "Complete LPI Security Essentials Exam Study Guide" course on Udemy, I'll admit that I initially had questions about the certification objectives:

◉ If the primary target candidates were technology consumers rather than administrators, why were they expected to understand relatively complex topics like specific encryption algorithms or TCP/IP addressing?

◉ Why were some critical hands-on security skills (such as event log analysis) missing from the objectives?

◉ What would people be able to do with the certification? I ascertained that there wasn't enough deeply technical content in the Essentials certification to fully prepare a candidate for a career in IT security.

As I worked through the objectives in the process of building my own book and course content, I developed an answer to my first question about complex topics along with a better sense of the exceptional value the certification offers. There are a thousand ways that our personal data, smartphones, laptops, online accounts, and identities can be compromised. Without at least a basic understanding of each threat category, how will we even identify the signs of an attack? There are all kinds of tools - many of them available for free - we can use to protect ourselves. But without at least some familiarity with their functioning, we’re not likely to know when (and how) to adopt them.

Some topics - such as encryption technologies in WiFi networks, web browsers, and email clients - just can't be overly simplified without losing sight of the point. After thinking it through, I’ve decided that the objectives did a great job finding the right balance for their target audience. Sure, understanding the differences between the RSA and AES algorithms can feel a bit too far down the rabbit hole. But there are perfectly practical applications.

What about the missing information needed by administrators? The LPI Security Essentials was definitely not designed to produce IT security professionals, but it could guide candidates through their first steps toward that goal if they decided it made sense for them. In fact, the objectives do a great job lightly covering a very wide range of relevant topics in case any of them comes up in your daily activities. That's not unlike the way the LPIC Linux administration objectives cover some tools that I've never encountered in my years as an admin. But I can tell you that I definitely appreciated knowing about the tools that I did end up using.

So now more than ever I'm convinced that a well-designed set of objectives is worth the time and expense involved in getting yourself to the exam. The certification you get after completing the exam is just icing on the cake. And I'm confident telling you that the LPI Security Essentials is in fact, well-designed.
